 Changelog
 =========
 
-current (development) 
----------------------
+Next
+====
+
+### Doc
+- Fix broken Doxygen output. See @markmandel in #1029.
+- Use Doxygen awesome. Add our own theme.
+- Break the documentation into several pages.
+
+### Build
+- Feature: Support C++20 modules. 
+  This requires:
+  - Using the Ninja or MSVC generator
+  - A recent Clang/GCC/MSVC compiler.
+  - Cmake 3.28 or higher.
+  Usage:
+  ```cpp
+  import ftxui;
+  import ftxui.component;
+  import ftxui.dom;
+  import ftxui.screen;
+  import ftxui.util;
+  ```
+  Thanks @mikomikotaishi for PR #1015.
+- Remove dependency on 'pthread'.
+
+### Component
+- Fix ScreenInteractive::FixedSize screen stomps on the preceding terminal
+  output. Thanks @zozowell in #1064.
+- Fix vertical `ftxui::Slider`. The "up" key was previously decreasing the
+  value. Thanks @its-pablo in #1093 for reporting the issue.
+
+
+6.1.9 (2025-05-07)
+------------
+
+### Build
+If all goes well (pending), ftxui should appear in the Bazel central repository.
+It can be imported into your project using the following lines:
+
+**MODULE.bazel**
+```bazel
+bazel_dep(name = "ftxui", version = "6.1.9")
+```
+
+Thanks @robinlinden and @kcc for the reviews.
+
+### dom
+- Bugfix: Restore the `dbox` behavior from ftxui 5.0.0. To apply bgcolor
+  blending between the two layers, a new `dboxBlend` will be added.
+
+6.1.8 (2025-05-01)
+------------------
+
+### Build
+- Feature: Support `bazel` build system. See #1032.
+  Proposed by Kostya Serebryany @kcc
+
+  **BUILD.bazel**
+  ```bazel
+  deps = [
+    // Depend on the whole library:
+    "@ftxui//:ftxui",

+    "@ftxui//:dom",
+    "@ftxui//:screen",
+  ]
+  ```
+
+### Component
+- Bugfix: Fix a crash with ResizeableSplit. See #1023.
+  - Clamp screen size to terminal size.
+  - Disallow `ResizeableSplit` with negative size.
+
+### Dom
+- Bugfix: Disallow specifying a negative size constraint. See #1023.
+
+
+6.0.2 (2025-03-30)
+-----

+- BugFix: Fix major crash on Windows affecting all components. See #1020
+- BugFix: Fix focusRelative.
+
+6.0.1 (2025-03-28)
+-----
+
+Same as v6.0.0.
+
+Due to a problem tag v6.0.0 was replaced. This isn't a good practice and affect
+developers that started using it in the short timeframe. Submitting a new
+release with the same content is the best way to fix this.
+
+See #1017 and #1019.

+
+
+> [!WARNING]
+> This feature is still in development, and the API may change in future releases.
+> Your contribution is needed to help us improve the compatibility and usability
+> of C++20 modules in FTXUI. If you encounter any issues or have suggestions,
+> please open an issue.
+
+FTXUI experimentally supports
+[C++20 modules](https://en.cppreference.com/w/cpp/language/modules) to reduce
+compilation times and improve code organization. Each header has a
+corresponding module.
+
+Use the FTXUI_BUILD_MODULES option to build the FTXUI project itself to provide C++ 20 modules,
+for example with CMake and Ninja:
+
+```sh
+cmake \
+    -DCMAKE_GENERATOR=Ninja \
+    -DFTXUI_BUILD_MODULES=ON \
+    ..
+
+ninja
+```
+
+> [!NOTE]
+> To use modules, you need a C++20 compatible compiler, CMake version 3.20 or
+> higher, and use a compatible generator like Ninja. Note that Makefile
+> generators **do not support modules**.
+
+Then, in your own code you can consume the modules and code as normal:
+
+```cpp
+import ftxui;
+
+int main() {
+  auto screen = ftxui::ScreenInteractive::TerminalOutput();
+  auto button = ftxui::Button("Click me", screen.QuitClosure());
+  screen.Loop(button);
+  return 0;
+}
+```
+
+Note, the `ftxui` convenience module which simply pulls together all the modules:
+
+```cpp
+export import ftxui.component;
+export import ftxui.dom;
+export import ftxui.screen;
+export import ftxui.util;
+```
+You can instead import only the module(s) you need if desired.
+
+To properly find and link the modules with CMake, use `target_link_libraries` to get the right
+compiler, linker, etc. flags.
+
+```cmake
+target_link_libraries(my_executable
+    #...whatever...
+    PRIVATE ftxui::modules
+)
+```
+
+### Module list
+
+The modules directly reference the corresponding header, or a group of related
+headers to provide a more convenient interface. The following modules
+are available:
+
+- `ftxui`
+    - `ftxui.component`
+      - `ftxui.component.Animation`
+      - `ftxui.component.CapturedMouse`

+      - `ftxui.component.Receiver`
+      - `ftxui.component.ScreenInteractive`
+      - `ftxui.component.Task`

+
+# Install FTXUI
+
+To set up FTXUI in your project, follow the [installation guide](installation.html), which provides instructions for multiple build systems and package managers.
+
+# Minimal Example
+
+Save the following code as `main.cpp`:
+
+```cpp
+#include <ftxui/dom/elements.hpp>
+#include <ftxui/screen/screen.hpp>
+#include <iostream>
+
+int main() {
+  using namespace ftxui;
+
+  Element document = hbox({
+    text("left")   | border,
+    text("middle") | border | flex,
+    text("right")  | border,
+  });
+
+  auto screen = Screen::Create(Dimension::Full(), Dimension::Fit(document));
+  Render(screen, document);
+  screen.Print();
+}
+```
+
+Build and run it using your preferred build system.  
+If unsure, start with one of the methods described in the [installation page](installation.html).
+
+Expected output:
+
+```
+┌────┐┌────────────────────────────────────┐┌─────┐
+│left││middle                              ││right│
+└────┘└────────────────────────────────────┘└─────┘
+```
+
+# Starter Template
+
+For a complete working project, clone the official starter repository:
+
+```bash
+git clone https://github.com/ArthurSonzogni/ftxui-starter
+```
+
+Follow the build instructions in the `README.md` of that repository.

+This page explains how to depend on FTXUI using [CMake](https://cmake.org).  
+
+# Methods of Integration
+
+## Using FetchContent
+
+This approach downloads FTXUI at configure time and doesn't require a system-wide install.
+
+```cmake 
+include(FetchContent)
+
+FetchContent_Declare(ftxui
+  GIT_REPOSITORY https://github.com/ArthurSonzogni/FTXUI
+  GIT_TAG v6.1.9  # Replace with a version, tag, or commit hash

+If FTXUI is installed system-wide or via a package manager (e.g. vcpkg or Conan), you can use:
+
+```cmake 
+find_package(ftxui REQUIRED)
+
+add_executable(main main.cpp)
+target_link_libraries(main
+  PRIVATE ftxui::screen
+  PRIVATE ftxui::dom
+  PRIVATE ftxui::component
+)
+```
+
+Make sure the package is visible in your `CMAKE_PREFIX_PATH`.
+
+## Using git submodule
+
+You can also add FTXUI as a [Git submodule](https://git-scm.com/book/en/v2/Git-Tools-Submodules), keeping it as part of your repository:
+
+```cmake
+git submodule add https://github.com/ArthurSonzogni/FTXUI external/ftxui
+git submodule update --init --recursive
+```
+
+When cloning a repository that already includes FTXUI as a submodule, make sure to fetch submodules with:
+
+```
+git clone --recurse-submodules <your-repo>
+# Or, if already cloned:
+git submodule update --init --recursive
+```
+
+Then in your `CMakeLists.txt`:
+
+```cmake
+add_subdirectory(external/ftxui)
+
+add_executable(main main.cpp)
+target_link_libraries(main
+  PRIVATE ftxui::screen
+  PRIVATE ftxui::dom
+  PRIVATE ftxui::component
+)
+```
+
+This approach works well if you want to vendor FTXUI in your own repository.
+
+# Optional CMake Flags
+
+FTXUI supports the following CMake options:
+
+| Option                            | Description                   | Default |

+@tableofcontents
+
+FTXUI can be easily obtained and integrated into your project using the Conan package manager.
+
+## Prerequisites
+
+First, ensure that Conan is installed on your system. If not, you can install it via pip:
+
+```powershell
+pip install conan
+```
+Conan often works in tandem with CMake, so you will need to have CMake installed as well. Once you have confirmed both Conan and CMake are installed, create a project directory, for example, `ftxui-demo`:
+
+```powershell
+mkdir C:\ftxui-demo
+cd C:\ftxui-demo
+```
+
+## Configuration
+
+After ensuring your environment is set up correctly, create a Conan configuration file `conanfile.txt`. This file is used to declare your project's dependencies. The community-maintained package for FTXUI can be found on [Conan Center](https://conan.io/center/recipes/ftxui).
+
+> [!note]
+> This is an unofficial build script. This means it is not maintained by the FTXUI
+> team but by the community. The package maintainer appears to actively update it
+> to the latest releases. Many thanks to the maintainer for their work!
+
+@todo If you are familiar with the process, please consider adding an "official" build script to Conan Center.
+This could be a GitHub Action that automatically updates Conan Center upon new releases.
+
+```ini
+[requires]
+ftxui/6.0.2
+
+[generators]
+CMakeDeps
+CMakeToolchain
+
+[layout]
+cmake_layout
+```
+
+## Install Dependencies and Build
+
+Once configured, run the following command to install FTXUI and its dependencies:
+
+```powershell
+conan install . --output-folder=build --build=missing
+```
+
+This will download and install `ftxui/6.0.2` along with all its dependencies from Conan's remote repositories.
+
+After the installation completes, you can test it by creating a `demo.cpp` file in your project directory:
+
+```cpp
+#include <ftxui/screen/screen.hpp>
+#include <ftxui/dom/elements.hpp>
+#include <iostream>
+
+int main() {
+    using namespace ftxui;
+    auto document = hbox({
+        text(" Hello "),
+        text("FTXUI ") | bold | color(Color::Red),
+        text(" world! ")
+    });
+    auto screen = Screen::Create(Dimension::Full(), Dimension::Fit(document));
+    Render(screen, document);
+    std::cout << screen.ToString() << std::endl;
+    return 0;
+}
+```
+
+If the test is successful, you can then create a `CMakeLists.txt` file in the project directory:
+
+```cmake
+cmake_minimum_required(VERSION 3.20)
+project(ftxui-demo)
+
+# Set the C++ standard
+set(CMAKE_CXX_STANDARD 20)
+
+# Find the FTXUI package installed via Conan
+find_package(ftxui CONFIG REQUIRED)
+
+# Create the executable
+add_executable(demo demo.cpp)
+
+# Link the executable to the FTXUI library
+target_link_libraries(demo PRIVATE ftxui::component)
+```
+
+@todo 考虑到中国多数地区使用Conan很有可能遇到各种网络问题，我想做一个定制的版本说明，但是我对conan的了解有限再加上没有找到合适的资料，因此这个计划短暂的被搁置了，如果您知道方法，欢迎在[中文版本](xiaoditx.girhub.io/public/docs/ftxui%E4%B8%AD%E6%96%87%E7%BF%BB%E8%AF%91/installation/conan/)的下方留下评论以提醒我

+
+**FTXUI** is simple cross-platform C++ library for terminal based user interfaces!
+
+# Feature
+ * Functional style. Inspired by
+   [1](https://hackernoon.com/building-reactive-terminal-interfaces-in-c-d392ce34e649?gi=d9fb9ce35901)
+   and [React](https://reactjs.org/)
+ * No dependencies
+ * **Cross platform**.
+ * Simple and elegant syntax (in my opinion)
+ * Keyboard & mouse navigation.
+ * Support for [UTF8](https://en.wikipedia.org/wiki/UTF-8) and [fullwidth chars](https://en.wikipedia.org/wiki/Halfwidth_and_fullwidth_forms) (→ 测试)
+ * Support for animations. [Demo 1](https://arthursonzogni.github.io/FTXUI/examples/?file=component/menu_underline_animated_gallery), [Demo 2](https://arthursonzogni.github.io/FTXUI/examples/?file=component/button_style)
+ * Support for drawing. [Demo](https://arthursonzogni.github.io/FTXUI/examples/?file=component/canvas_animated)
+ * Learn by [examples](#documentation), and [tutorials](#documentation)
+ * Multiple build system and packages: 
+ * Good practices: documentation, tests, fuzzers, performance tests, automated CI, automated packaging, etc...
+
+# Example
+
+```cpp
+#include <ftxui/dom/elements.hpp>
+#include <ftxui/screen/screen.hpp>
+#include <iostream>
+

-
-Welcome to the FTXUI documentation!
-
-This is a brief tutorial. You are also encouraged to self-learn by reading the
-[examples](./examples.html).
-
-@tableofcontents 
-
-**Short example**
-
-To build a single frame, you need create an `ftxui::Element`, and display it on
-a `ftxui::Screen`.
-
-**main.cpp**
-```cpp
-#include <ftxui/dom/elements.hpp>
-#include <ftxui/screen/screen.hpp>
-#include <iostream>
-
-int main(void) {

-
-  // Define the document
-  Element document =
-    hbox({
-      text("left")   | border,
-      text("middle") | border | flex,
-      text("right")  | border,
-    });
-
-  auto screen = Screen::Create(
-    Dimension::Full(),       // Width

-
-```
-
-Subsequently, you build the project in the standard fashion as follows:
-```bash
-mkdir build && cd build
-cmake ..
-make
-./main
-```
-
-# List of modules. {#modules}
-
-The project is comprised of 3 modules:
-
-1. **ftxui/screen** defines a `ftxui::Screen`, a grid of `ftxui::Pixel`.
-
-2. **ftxui/dom** is the main module. It defines a hierarchical set of
-   `ftxui::Element`.  An element draws something on the `ftxui::Screen`. It is
-   responsive to the size of its container.
-
-3. **ftxui/component** The module is required if your program needs to respond
-   to user input. It defines a set of `ftxui::Component`. These components can
-   be utilized to navigate using the arrow keys *and/or* cursor. There are 
-   several builtin widgets like checkbox/inputbox/etc to interact with. You can
-   combine them, or even define your own custom components.
-
-# screen {#module-screen}
-
-This is the visual element of the program. It defines a `ftxui::Screen`, which
-is a grid of `ftxui::Pixel`. A Pixel represents a Unicode character and its
-associated style (bold, colors, etc.). The screen can be printed as a string
-using `ftxui::Screen::ToString()`. The following example highlights this
-process:
-
-```cpp
-  #include <ftxui/screen/screen.hpp>
-  #include <iostream>
-
-  int main(void) {
-    using namespace ftxui;
-    auto screen = Screen::Create(Dimension::Fixed(32), Dimension::Fixed(10));
-
-    auto& pixel = screen.PixelAt(9,9);
-    pixel.character = U'A';
-    pixel.bold = true;
-    pixel.foreground_color = Color::Blue;
-
-    std::cout << screen.ToString();
-    return EXIT_SUCCESS;
-  }
-```
-
-# dom {#module-dom}
-
-This module defines a hierarchical set of `ftxui::Element`. An element manages
-the layout and can be responsive to the terminal dimension changes. Note the
-following example where this module is used to create a simple layout with a
-number of operators:
-
-**Example:**
-```cpp
-// Define the document
-Element document = vbox({
-  text("The window") | bold | color(Color::Blue),
-  gauge(0.5)
-  text("The footer")
-});
-
-// Add a border, by calling the `ftxui::border` decorator function.
-document = border(document);
-
-// Add another border, using the pipe operator.
-document = document | border.
-
-// Add another border, using the |= operator.
-document |= border
-
-```
-
-**List of elements**
-
-The list of all elements are included and can be accessed by including the
-corresponding header file:
-```cpp
-#include <ftxui/dom/elements.hpp>
-```
-
-\include ftxui/dom/elements.hpp
-
-## text ## {#dom-text}
-
-The most simple widget. It displays a text.
-```cpp
-text("I am a piece of text");
-```
-```bash
-I am a piece of text.
-```
-
-## vtext {#dom-vtext}
-
-Identical to `ftxui::text`, but displayed vertically.
-
-Code:
-```cpp
-vtext("HELLO");
-```
-
-Terminal output:
-```bash
-H
-E
-L
-L
-O
-```
-
-## paragraph {#dom-paragraph}
-
-Similar to `ftxui::text`, but the individual word are wrapped along multiple
-lines, depending on the width of its container.
-
-Sample Code:
-```cpp
-paragraph("A very long text")
-```
-
-![ezgif com-gif-maker (4)](https://user-images.githubusercontent.com/4759106/147251370-983a06e7-6f41-4113-92b8-942f43d34d06.gif)
-
-For a more detailed example refer to [detailed example](https://arthursonzogni.github.io/FTXUI/examples_2dom_2paragraph_8cpp-example.html). Paragraph also includes a number of other variants as shown below:
-```cpp
-Element paragraph(std::string text);
-Element paragraphAlignLeft(std::string text);
-Element paragraphAlignRight(std::string text);
-Element paragraphAlignCenter(std::string text);
-Element paragraphAlignJustify(std::string text);
-```
-
-
-## border {#dom-border}
-
-Adds a border around an element.
-
-Code:
-```cpp
-border(text("The element"))
-```
-
-Terminal output:
-```bash
-┌───────────┐
-│The element│
-└───────────┘
-```
-
-You can achieve the same behavior by using the pipe operator.
-
-Code:
-```cpp
-text("The element") | border
-```
-
-Border also comes in a variety of styles as shown below:
-```cpp

-## window ## {#dom-window}
-
-A `ftxui::window` is a `ftxui::border`, but with an additional header. To add a
-window around an element, wrap it and specify a string as the header.
-Code:
-```cpp
-window("The window", text("The element"))
-```
-
-Terminal output:
-```bash
-┌The window─┐
-│The element│
-└───────────┘
-```
-
-## separator {#dom-separator}
-
-Displays a vertical/horizontal line to visually split the content of a
-container in two.
-
-Code:
-```cpp
-border(
-  hbox({
-    text("Left"), 
-    separator(),
-    text("Right")
-  })
-)
-```
-
-Terminal output:
-```bash

-Most terminal consoles can display colored text and colored backgrounds. FTXUI
-supports every color palette:
-```cpp
-Decorator color(Color);
-Decorator bgcolor(Color);
-```
-
-
-Color [gallery](https://arthursonzogni.github.io/FTXUI/examples_2dom_2color_gallery_8cpp-example.html):
-![image](https://user-images.githubusercontent.com/4759106/147248595-04c7245a-5b85-4544-809d-a5984fc6f9e7.png)
-
-### Palette16 #{#dom-colors-palette-16}
-
-On most terminals the following colors are supported:
-- Default
-
-- Black
-- GrayDark
-- GrayLight
-
-- White
-
-- Blue
-- BlueLight
-
-- Cyan
-- CyanLight
-
-- Green
-- GreenLight
-
-- Magenta
-- MagentaLight
-
-- Red
-- RedLight
-
-- Yellow
-- YellowLight
-
-Example use of the above colors using the pipe operator:
-```cpp
-text("Blue foreground") | color(Color::Blue);
-text("Blue background") | bgcolor(Color::Blue);
-text("Black on white") | color(Color::Black) | bgcolor(Color::White);
-```
-
-### Palette256 #{#dom-colors-palette-256}
-
-On terminal supporting 256 colors.

-
-```cpp
-text("HotPink") | color(Color::HotPink);
-```
-
-### TrueColor #{#dom-colors-true-color}
-
-On terminal supporting trueColor, you can directly use the 24bit RGB color
-space:
-
-Use the constructors below to specify the **RGB** or **HSV** values for your
-color:
-
-There are two constructors:
-```cpp
-ftxui::Color::RGB(uint8_t red, uint8_t green, uint8_t blue);
-ftxui::Color::HSV(uint8_t hue, uint8_t saturation, uint8_t value);
-```

-
-## LinearGradient #{#dom-linear-gradient}
-
-FTXUI supports linear gradient. Either on the foreground or the background.
-
-```cpp
-Decorator color(const LinearGradient&);
-Decorator bgcolor(const LinearGradient&);
-```
-
-A `ftxui::LinearGradient` is defined by an angle in degree, and a list of color
-stops.
-```cpp
-auto gradient = LinearGradient()
-  .Angle(45)
-  .AddStop(0.0, Color::Red)
-  .AddStop(0.5, Color::Green)
-  .AddStop(1.0, Color::Blue);
-```
-
-You can also use simplified constructors:
-```cpp
-LinearGradient(Color::Red, Color::Blue);
-```
-```cpp
-LinearGradient(45, Color::Red, Color::Blue);
-```
-
-See [demo](https://arthursonzogni.github.io/FTXUI/examples/?file=component/linear_gradient_gallery).
-
-
-## Style {#dom-style}
-In addition to colored text and colored backgrounds. Many terminals support text
-effects such as: `bold`, `dim`, `underlined`, `inverted`, `blink`.
-
-```cpp
-Element bold(Element);
-Element dim(Element);
-Element inverted(Element);
-Element underlined(Element);
-Element underlinedDouble(Element);
-Element strikethrough(Element);
-Element blink(Element);
-Decorator color(Color);
-Decorator bgcolor(Color);
-Decorator colorgrad(LinearGradient);
-Decorator bgcolorgrad(LinearGradient);
-```
-
-[Example](https://arthursonzogni.github.io/FTXUI/examples_2dom_2style_gallery_8cpp-example.html)
-

-
-To use these effects, simply wrap your elements with your desired effect:
-```cpp
-underlined(bold(text("This text is bold and underlined")))
-```
-
-Alternatively, use the pipe operator to chain it on your element:
-```cpp
-text("This text is bold") | bold | underlined
-```
-
-## Layout {#dom-layout}
-
-Enables elements to be arranged in the following ways:
-  - **Horizontally** with `ftxui::hbox`
-  - **Vertically** with `ftxui::vbox`
-  - **Inside a grid** with `ftxui::gridbox`
-  - **Wrapped along one direction** using the `ftxui::flexbox`.
-  
-[Example](https://arthursonzogni.github.io/FTXUI/examples_2dom_2vbox_hbox_8cpp-example.html) using `ftxui::hbox`, `ftxui::vbox` and `ftxui::filler`.

-# component {#module-component}
-
-The `ftxui::component` module defines the logic that produces interactive
-components that respond to user events (keyboard, mouse, etc.).
-
-A `ftxui::ScreenInteractive` defines a main loop that renders a component.
-
-A `ftxui::Component` is a shared pointer to a `ftxui::ComponentBase`. The latter defines:
-  - `ftxui::ComponentBase::Render()`: How to render the interface.
-  - `ftxui::ComponentBase::OnEvent()`: How to react to events.
-  - `ftxui::ComponentBase::Add()`: Construct a parent/child relationship
-    between two components. The tree of component is used to define how to
-    navigate using the keyboard.
-
-`ftxui::Element` are used to render a single frame.
-
-`ftxui::Component` are used to render dynamic user interface, producing multiple
-frame, and updating its state on events.

-
-## Renderer {#component-renderer}
-
-Produced by: `ftxui::Renderer()` from \ref ftxui/component/component.hpp. This
-component decorate another one by using a different function to render an
-interface.
-
-Example:
-```cpp
-auto inner = [...]
-
-auto renderer = Renderer(inner, [&] {
-  return inner->Render() | border
-});
-```
-
-`ftxui::Renderer` also supports the component decorator pattern:
-```cpp
-auto component = [...]
-component = component
-  | Renderer([](Element e) { return e | border))
-  | Renderer(bold)
-```
-
-As a short hand, you can also compose a component with an element decorator:
-```cpp
-auto component = [...]
-component = component | border | bold;
-```
-
-## CatchEvent {#component-catchevent}
-
-Produced by: `ftxui::CatchEvent()` from \ref ftxui/component/component.hpp.
-This component decorate others, catching events before the underlying component.
-
-Examples:
-```cpp
-auto screen = ScreenInteractive::TerminalOutput();
-auto renderer = Renderer([] {
-  return text("My interface");
-});
-auto component = CatchEvent(renderer, [&](Event event) {
-  if (event == Event::Character('q')) {
-    screen.ExitLoopClosure()();
-    return true;
-  }
-  return false;
-});
-screen.Loop(component);
-```
-
-The `ftxui::CatchEvent` can also be used as a decorator:
-```cpp
-component = component
-  | CatchEvent(handler_1)
-  | CatchEvent(handler_2)
-  | CatchEvent(handler_3)
-  ;
-```
-
-## Collapsible {#component-collapsible}
-
-Useful for visual elements whose visibility can be toggle on/off by the user.
-Essentially, this the combination of the `ftxui::Checkbox()` and
-`ftxui::Maybe()` components.
-
-```cpp
-auto collabsible = Collapsible("Show more", inner_element);
-```
-
-## Maybe {#component-maybe}
-
-Produced by: `ftxui::Maybe()` from \ref ftxui/component/component.hpp.
-This component can be utilized to show/hide any other component via a boolean or
-a predicate.
-
-Example with a boolean:
-```cpp
-bool show = true;
-auto component = Renderer([]{ return "Hello World!"; });
-auto maybe_component = Maybe(component, &show)
-```
-
-Example with a predicate:
-```cpp
-auto component = Renderer([]{ return "Hello World!"; });
-auto maybe_component = Maybe(component, [&] { return time > 10; })
-```
-
-As usual, `ftxui::Maybe` can also be used as a decorator:
-```cpp
-component = component
-  | Maybe(&a_boolean)
-  | Maybe([&] { return time > 10; })
-  ;
-```
-
-## Container {#component-container}
-
-### Horizontal {#component-horizontal}
-
-Produced by: `ftxui::Container::Horizontal()` from
-"ftxui/component/component.hpp". It displays a list of components horizontally
-and handle keyboard/mouse navigation.
-
-### Vertical {#component-vertical}
-
-Produced by: `ftxui::Container::Vertical()` from
-"ftxui/component/component.hpp". It displays a list of components vertically 
-and handles keyboard/mouse navigation.
-
-### Tab {#component-tab}
-
-Produced by: `ftxui::Container::Tab()` from
-"ftxui/component/component.hpp". It take a list of component and display only
-one of them. This is useful for implementing a tab bar.

-## ResizableSplit  {#component-resizable-split}
-
-It defines a horizontal or vertical separation between two children components.
-The position of the split is variable and controllable using the mouse. 
-There are four possible splits:
-- `ftxui::ResizableSplitLeft()`
-- `ftxui::ResizableSplitRight()`
-- `ftxui::ResizableSplitTop()`
-- `ftxui::ResizableSplitBottom()`

-## Force a frame redraw. {#component-force-redraw}
-
-Typically, `ftxui::ScreenInteractive::Loop()` is responsible for drawing a new
-frame whenever a new group of events (e.g keyboard, mouse, window resize, etc.)
-has been processed. However, you might want to react to arbitrary events that
-are unknown to FTXUI. To accomplish this, you must post events using
-`ftxui::ScreenInteractive::PostEvent` (**this is thread safe**) via a thread.
-You will have to post the event `ftxui::Event::Custom`.
-
-Example:
-```cpp
-screen->PostEvent(Event::Custom);
-```

+# Dropdown {#component-dropdown}
+
+A drop-down menu is a component that, when opened, displays a list of elements
+for the user to select from.
+

+
+# Slider {#component-slider}
+
+Represents a slider object that consists of a range with binned intermediate
+intervals. It can be created by `ftxui::Slider()`.
+
+[Example](https://arthursonzogni.github.io/FTXUI/examples_2component_2slider_8cpp-example.html):
+
+![image](https://user-images.githubusercontent.com/4759106/147249265-7e2cad75-082c-436e-affe-44a550c480ab.png)
+
+Produced by: `ftxui::Slider()` from "ftxui/component/component.hpp"
+
+# Renderer {#component-renderer}
+
+Produced by: `ftxui::Renderer()` from \ref ftxui/component/component.hpp. This
+component decorate another one by using a different function to render an
+interface.
+
+Example:
+```cpp
+auto inner = [...]
+
+auto renderer = Renderer(inner, [&] {
+  return inner->Render() | border
+});
+```
+
+`ftxui::Renderer` also supports the component decorator pattern:
+```cpp
+auto component = [...]
+component = component
+  | Renderer([](Element e) { return e | border))
+  | Renderer(bold)
+```
+
+As a short hand, you can also compose a component with an element decorator:
+```cpp
+auto component = [...]
+component = component | border | bold;
+```
+
+# CatchEvent {#component-catchevent}
+
+Produced by: `ftxui::CatchEvent()` from \ref ftxui/component/component.hpp.
+This component decorate others, catching events before the underlying component.
+
+Examples:
+```cpp
+auto screen = ScreenInteractive::TerminalOutput();
+auto renderer = Renderer([] {
+  return text("My interface");
+});
+auto component = CatchEvent(renderer, [&](Event event) {
+  if (event == Event::Character('q')) {
+    screen.ExitLoopClosure()();
+    return true;
+  }
+  return false;
+});
+screen.Loop(component);
+```
+
+The `ftxui::CatchEvent` can also be used as a decorator:
+```cpp
+component = component
+  | CatchEvent(handler_1)
+  | CatchEvent(handler_2)
+  | CatchEvent(handler_3)
+  ;
+```
+
+# Collapsible {#component-collapsible}
+
+Useful for visual elements whose visibility can be toggled on or off by the
+user. Essentially, this is the combination of the `ftxui::Checkbox()` and
+`ftxui::Maybe()` components.
+
+```cpp
+auto collapsible = Collapsible("Show more", inner_element);
+```
+
+# Maybe {#component-maybe}
+
+Produced by: `ftxui::Maybe()` from \ref ftxui/component/component.hpp.
+This component can be utilized to show/hide any other component via a boolean or
+a predicate.
+
+Example with a boolean:
+```cpp
+bool show = true;
+auto component = Renderer([]{ return "Hello World!"; });
+auto maybe_component = Maybe(component, &show)
+```
+
+Example with a predicate:
+```cpp
+auto component = Renderer([]{ return "Hello World!"; });
+auto maybe_component = Maybe(component, [&] { return time > 10; })
+```
+
+As usual, `ftxui::Maybe` can also be used as a decorator:
+```cpp
+component = component
+  | Maybe(&a_boolean)
+  | Maybe([&] { return time > 10; })
+  ;
+```
+
+# Container {#component-container}
+
+## Horizontal {#component-horizontal}
+
+Produced by: `ftxui::Container::Horizontal()` from
+"ftxui/component/component.hpp". It displays a list of components horizontally
+and handles keyboard/mouse navigation.
+
+## Vertical {#component-vertical}
+
+Produced by: `ftxui::Container::Vertical()` from
+"ftxui/component/component.hpp". It displays a list of components vertically 
+and handles keyboard/mouse navigation.
+
+## Tab {#component-tab}
+
+Produced by: `ftxui::Container::Tab()` from
+"ftxui/component/component.hpp". It takes a list of components and displays
+only one of them. This is useful for implementing a tab bar.
+

+
+
+# ResizableSplit  {#component-resizable-split}
+
+It defines a horizontal or vertical separation between two children components.
+The position of the split is variable and controllable using the mouse. 
+There are four possible splits:
+- `ftxui::ResizableSplitLeft()`
+- `ftxui::ResizableSplitRight()`
+- `ftxui::ResizableSplitTop()`
+- `ftxui::ResizableSplitBottom()`
+from "ftxui/component/component.hpp"

+
+# Force a frame redraw. {#component-force-redraw}
+
+Typically, `ftxui::ScreenInteractive::Loop()` is responsible for drawing a new
+frame whenever a new group of events (e.g keyboard, mouse, window resize, etc.)
+has been processed. However, you might want to react to arbitrary events that
+are unknown to FTXUI. To accomplish this, you must post events using
+`ftxui::ScreenInteractive::PostEvent` (**this is thread safe**) via a thread.
+You will have to post the event `ftxui::Event::Custom`.
+
+Example:
+```cpp
+screen->PostEvent(Event::Custom);
+```
+
+If you don't need to process a new Event, you can use:
+```cpp
+screen->RequestAnimationFrame();
+```
+instead.

+
+This module defines a hierarchical set of `ftxui::Element`. An element manages
+the layout and can be responsive to the terminal dimension changes. Note the
+following example where this module is used to create a simple layout with a
+number of operators:
+
+The @subpage module-dom-examples section provides a collection of examples.
+
+**Example:**
+```cpp
+namespace ftxui {
+    ...
+
+// Define the document
+Element document = vbox({
+  text("The window") | bold | color(Color::Blue),
+  gauge(0.5)
+  text("The footer")
+});
+
+// Add a border, by calling the `ftxui::border` decorator function.
+document = border(document);
+
+// Add another border, using the pipe operator.
+document = document | border.
+
+// Add another border, using the |= operator.
+document |= border
+
+...
+}
+```
+
+**List of elements**
+
+The list of all elements are included and can be accessed by including the
+corresponding header file:
+```cpp
+#include <ftxui/dom/elements.hpp>
+```
+
+\include{strip} "ftxui/dom/elements.hpp"
+
+# text # {#dom-text}
+
+The most simple widget. It displays a text.
+```cpp
+text("I am a piece of text");
+```
+```bash
+I am a piece of text.
+```
+
+# vtext {#dom-vtext}
+
+Identical to `ftxui::text`, but displayed vertically.
+
+Code:
+```cpp
+vtext("HELLO");
+```
+
+Terminal output:
+```bash
+H
+E
+L
+L
+O
+```
+
+# paragraph {#dom-paragraph}
+
+Similar to `ftxui::text`, but the individual word are wrapped along multiple
+lines, depending on the width of its container.
+
+Sample Code:
+```cpp
+paragraph("A very long text")
+```
+

+
+For a more detailed example refer to [detailed example](https://arthursonzogni.github.io/FTXUI/examples_2dom_2paragraph_8cpp-example.html). Paragraph also includes a number of other variants as shown below:
+```cpp
+namespace ftxui {
+    Element paragraph(std::string text);
+    Element paragraphAlignLeft(std::string text);
+    Element paragraphAlignRight(std::string text);
+    Element paragraphAlignCenter(std::string text);
+    Element paragraphAlignJustify(std::string text);
+}
+```
+
+
+# border {#dom-border}
+
+Adds a border around an element.
+
+Code:
+```cpp
+border(text("The element"))
+```
+
+Terminal output:
+```bash
+┌───────────┐
+│The element│
+└───────────┘
+```
+
+> [!note]
+> You can achieve the same behavior by using the pipe operator.
+> 
+> Code:
+> ```cpp
+> text("The element") | border
+> ```
+
+Border also comes in a variety of styles as shown below:
+```cpp
+namespace ftxui {
+    Element border(Element);
+    Element borderLight(Element);
+    Element borderHeavy(Element);
+    Element borderDouble(Element);
+    Element borderRounded(Element);
+    Element borderEmpty(Element);
+    Decorator borderStyled(BorderStyle);
+    Decorator borderWith(Pixel);
+}
+```
+
+
+# window # {#dom-window}
+
+A `ftxui::window` is a `ftxui::border`, but with an additional header. To add a
+window around an element, wrap it and specify a string as the header.
+Code:
+```cpp
+window("The window", text("The element"))
+```
+
+Terminal output:
+```bash
+┌The window─┐
+│The element│
+└───────────┘
+```
+
+# separator {#dom-separator}
+
+Displays a vertical/horizontal line to visually split the content of a
+container in two.
+
+Code:
+```cpp
+border(
+  hbox({
+    text("Left"), 
+    separator(),
+    text("Right")
+  })
+)
+```
+
+Terminal output:
+```bash
+┌────┬─────┐
+│left│right│
+└────┴─────┘
+```
+
+
+Separators come in a variety of flavors as shown below:
+```cpp
+namespace ftxui {
+    Element separator(void);
+    Element separatorLight();
+    Element separatorHeavy();
+    Element separatorDouble();
+    Element separatorEmpty();
+    Element separatorStyled(BorderStyle);
+    Element separator(Pixel);

+                               Color foreground);
+}
+```
+
+# gauge {#dom-gauge}
+
+This is a visual element that represents a ratio of progress.
+
+Code:
+```cpp
+border(gauge(0.5))
+```
+
+Terminal output:
+```bash
+┌────────────────────────────────────────────────────────────────────────────┐

+
+## Palette16 #{#dom-colors-palette-16}
+
+On most terminals the following colors are supported:
+- Default
+
+- Black
+- GrayDark
+- GrayLight
+
+- White
+
+- Blue
+- BlueLight
+
+- Cyan
+- CyanLight
+
+- Green
+- GreenLight

+text("Blue background") | bgcolor(Color::Blue);
+text("Black on white") | color(Color::Black) | bgcolor(Color::White);
+```
+
+## Palette256 #{#dom-colors-palette-256}

+
+## TrueColor #{#dom-colors-true-color}
+
+On terminal supporting trueColor, you can directly use the 24bit RGB color
+space:
+
+Use the constructors below to specify the **RGB** or **HSV** values for your
+color:
+
+There are two constructors:
+```cpp
+ftxui::Color::RGB(uint8_t red, uint8_t green, uint8_t blue);
+ftxui::Color::HSV(uint8_t hue, uint8_t saturation, uint8_t value);

+
+# LinearGradient #{#dom-linear-gradient}
+
+FTXUI supports linear gradient. Either on the foreground or the background.
+
+```cpp
+Decorator color(const LinearGradient&);
+Decorator bgcolor(const LinearGradient&);
+```
+
+A `ftxui::LinearGradient` is defined by an angle in degree, and a list of color
+stops.
+```cpp
+auto gradient = LinearGradient()
+  .Angle(45)
+  .AddStop(0.0, Color::Red)
+  .AddStop(0.5, Color::Green)
+  .AddStop(1.0, Color::Blue);
+```
+
+You can also use simplified constructors:
+```cpp
+LinearGradient(Color::Red, Color::Blue);
+```
+```cpp
+LinearGradient(45, Color::Red, Color::Blue);
+```
+
+See [demo](https://arthursonzogni.github.io/FTXUI/examples/?file=component/linear_gradient_gallery).
+
+
+# Style {#dom-style}
+In addition to colored text and colored backgrounds. Many terminals support text
+effects such as: `bold`, `italic`, `dim`, `underlined`, `inverted`, `blink`.
+
+```cpp
+Element bold(Element);
+Element italic(Element);
+Element dim(Element);
+Element inverted(Element);
+Element underlined(Element);
+Element underlinedDouble(Element);
+Element strikethrough(Element);
+Element blink(Element);
+Decorator color(Color);
+Decorator bgcolor(Color);
+Decorator colorgrad(LinearGradient);
+Decorator bgcolorgrad(LinearGradient);
+```

+
+To use these effects, simply wrap your elements with your desired effect:
+```cpp
+underlined(bold(text("This text is bold and underlined")))
+```
+
+Alternatively, use the pipe operator to chain it on your element:
+```cpp
+text("This text is bold") | bold | underlined
+```
+
+# Layout {#dom-layout}
+
+Enables elements to be arranged in the following ways:
+  - **Horizontally** with `ftxui::hbox`
+  - **Vertically** with `ftxui::vbox`
+  - **Inside a grid** with `ftxui::gridbox`
+  - **Wrapped along one direction** using the `ftxui::flexbox`.
+  
+[Example](https://arthursonzogni.github.io/FTXUI/examples_2dom_2vbox_hbox_8cpp-example.html) using `ftxui::hbox`, `ftxui::vbox` and `ftxui::filler`.

+
+The `ftxui::screen` module is the low-level foundation. It can be used
+standalone, but it is primarily designed to be used together by
+[ftxui::dom](module-dom.html) and [ftxui::component](module-component.html)
+modules.
+
+It provides a @ref ftxui::Screen.
+
+---
+
+# ftxui::Screen
+
+The @ref ftxui::Screen class represents a 2D grid of styled characters that can
+be rendered to a terminal.  
+It provides methods to create a screen, access pixels, and render elements.
+
+You can access the individual cells (@ref ftxui::Pixel) of the screen using 
+the @ref ftxui::Screen::PixelAt method, which returns a reference
+to the pixel at the specified coordinates.
+
+**Example**
+```cpp
+#include <ftxui/screen/screen.hpp>
+#include <ftxui/screen/color.hpp>
+
+void main() {
+    auto screen = ftxui::Screen::Create(
+        ftxui::Dimension::Full(),   // Use full terminal width
+        ftxui::Dimension::Fixed(10) // Fixed height of 10 rows
+    );
+
+    // Access a specific pixel at (10, 5)
+    auto& pixel = screen.PixelAt(10, 5);
+
+    // Set properties of the pixel.
+    pixel.character = U'X';
+    pixel.foreground_color = ftxui::Color::Red;
+    pixel.background_color = ftxui::Color::RGB(0, 255, 0);
+    pixel.bold = true; // Set bold style
+    screen.Print(); // Print the screen to the terminal
+}
+```
+
+> [!note]
+> If the coordinates are out of bounds, a dummy pixel is returned.
+
+The screen can be printed to the terminal using @ref ftxui::Screen::Print() or
+converted to a std::string with @ref ftxui::Screen::ToString().
+
+<div class="tabbed">
+ 
+- <b class="tab-title">Print()</b>
+  ```cpp
+  auto screen = ...;
+  screen.Print();
+  ```
+- <b class="tab-title">ToString()</b>
+  ```cpp
+  auto screen = ...;
+  std::cout << screen.ToString();
+  ```
+ 
+</div>
+
+Note that you can reset the cursor position to the top-left corner of the
+screen after printing by calling @ref ftxui::Screen::ResetCursorPosition().
+
+**Example**
+```cpp
+auto screen = ...;
+while(true) {
+  // Drawing operations:
+  ...
+  
+  // Print the screen to the terminal. Then reset the cursor position and the
+  // screen content.
+  std::cout << screen.ToString();
+  std::cout << screen.ResetCursorPosition(/*clear=*/true);
+  std::cout << std::flush;
+
+  // Sleep for a short duration to control the refresh rate.
+  std::this_thread::sleep_for(std::chrono::milliseconds(100));
+}
+```
+
+---
+
+# ftxui::Dimension
+
+The @ref ftxui::Dimension utility controls screen sizing:
+
+* `Dimension::Full()` — use full terminal width or height
+* `Dimension::Fit(element)` — size to fit the rendered @ref ftxui::Element
+* `Dimension::Fixed(n)` — use exactly `n` columns or rows
+
+These values are to be passed to `ftxui::Screen::Create()`.
+
+@ref ftxui::Screen::Create() provides two overloads:
+
+- `Screen::Create(Dimension)` sets both width and height to the same kind of dimension
+- `Screen::Create(Dimension width, Dimension height)` allows distinct control per axis
+
+```cpp
+auto screen = ftxui::Screen::Create(
+  ftxui::Dimension::Full(),      // width
+  ftxui::Dimension::Fixed(10)    // height
+);
+```
+
+Once created, render an element and display the result:
+
+```cpp
+ftxui::Render(screen, element);
+screen.Print();
+```
+
+---
+
+# ftxui::Pixel
+
+Each cell in the screen grid is a @ref ftxui::Pixel, which holds:
+
+- Unicode codepoint.
+    - `character`
+- @ref ftxui::Color:
+    - `foreground_color`
+    - `background_color`
+- Booleans:
+    - `blink`
+    - `bold`
+    - `dim`
+    - `italic`
+    - `inverted` (swap foreground and background colors)
+    - `underlined`
+    - `underlined_double`
+    - `strikethrough`
+
+
+```cpp
+auto screen = ftxui::Screen::Create(
+  ftxui::Dimension::Fixed(5),
+  ftxui::Dimension::Fixed(5),
+);
+
+auto& pixel = screen.PixelAt(3, 3);
+pixel.character = U'X';
+pixel.bold = true;
+pixel.foreground_color = ftxui::Color::Red;
+pixel.background_color = ftxui::Color::RGB(0, 255, 0);
+
+screen.Print();
+```
+
+> [!note]
+> `PixelAt(x, y)` performs bounds checking and returns a reference to the pixel
+> at the specified coordinate. If out-of-bounds, a dummy pixel reference is
+> returned.
+
+
+Each cell in the screen is a @ref ftxui::Pixel. You can modify them using:
+
+```cpp
+auto& pixel = screen.PixelAt(x, y);
+pixel.character = U'X';
+pixel.bold = true;
+pixel.foreground_color = Color::Red;
+```
+
+---
+
+# ftxui::Color
+
+The @ref ftxui::Color class is used to define foreground and background colors for each @ref ftxui::Pixel.
+
+It supports various color spaces and predefined palettes. FTXUI will
+dynamically fallback to the closest available color in the terminal if the
+requested color is not supported by the terminal.
+
+**Color Spaces**
+
+- **Default**: `ftxui::Color::Default` (terminal's default color)
+- **16-color palette** [Demo](https://arthursonzogni.github.io/FTXUI/examples/?file=dom/color_gallery):
+    - `ftxui::Color::Black`,
+    - `ftxui::Color::Red`,
+    - ...
+- **256-color palette** [Demo](https://arthursonzogni.github.io/FTXUI/examples/?file=dom/color_palette256):
+    - `ftxui::Color::Chartreuse1`,
+    - `ftxui::Color::DarkViolet`,
+    - ...
+- **True color** (24bit) [Demo](https://arthursonzogni.github.io/FTXUI/examples/?file=dom/color_truecolor_HSV:
+    - `ftxui::Color::RGB(uint8_t red, uint8_t green, uint8_t blue)`
+    - `ftxui::Color::HSV(uint8_t h, uint8_t s, uint8_t v)`.
+    
+
+> [!note]
+> You can query the terminal capability using @ref ftxui::Terminal::ColorSupport();
+>
+> This can manually be set using @ref ftxui::Terminal::SetColorSupport().

+FTXUI is organized into three modules, each building upon the previous:
+
+1. [ftxui/screen](#module-screen) - Low-level rendering
+2. [ftxui/dom](#module-dom) - Layout and composition
+3. [ftxui/component](#module-component) - User interaction
+
+---
+
+# ftxui/screen
+
+Defines:
+
+- **`ftxui::Screen`**: a 2D grid of styled characters.
+- **`ftxui::Pixel`**: the unit of rendering.
+- Helpers like `ftxui::Color` and `Dimension`.
+
+Use for direct terminal drawing and styling.

+- **`ftxui::Element`**: a tree structure for layout and UI.
+- Composable and responsive elements.
+- `Render()` to draw onto a `Screen`.
