//! # Yew Sidebar - Documentation
//!
//! Welcome to the official Yew Sidebar documentation. This library
//! provides a flexible and customizable sidebar component for your Yew applications.
//!
//! ## Usage
//!
//! To use the Yew Sidebar library, add the following dependency to your `Cargo.toml` file:
//!
//! ```sh
//! cargo add yew-sidebar
//! ```
//!
//! To integrate the library into your Yew application, you can use the `Sidebar` component.
//! Here's a simple example of how to use it:
//!
//! ```rust,no_run
//! use yew::prelude::*;
//! use yew_sidebar::{Sidebar, SidebarProps, MenuItem};
//!
//! // Your Yew component structure here...
//!
//! #[function_component]
//! pub fn MySidebarComponent() -> Html {
//!     // Your component logic here...
//!
//!     let menu_items = vec![
//!         MenuItem {
//!             icon: html! { /* Your icon HTML here */ },
//!             text: "Home",
//!             link: "/home",
//!             class: "your-menu-item-class",
//!             title: "Your Menu Title",
//!             submenus: vec![], // Nested MenuItem structures if needed
//!         },
//!         // Add more MenuItem structures as needed...
//!     ];
//!
//!     let sidebar_props = SidebarProps {
//!         fixed: false,
//!         sider_collapsed: false,
//!         title: "Your Sidebar Title",
//!         menu_items,
//!         // Customize other props as needed...
//!         // ...
//!         ..SidebarProps::default()
//!     };
//!
//!     html! {
//!         <Sidebar ..sidebar_props />
//!     }
//! }
//! ```
//!
//! For more detailed information, check the [examples] provided in the library.
//!
//! [examples]: https://github.com/next-rs/yew-sidebar/examples
//!
//! ## Configuration
//!
//! Yew Sidebar allows you to configure various aspects of the sidebar through the `SidebarProps`
//! structure. You can customize properties such as width, padding, display, styling, icons, and more.
//! Refer to the `SidebarProps` documentation for detailed configuration options.
//!
//! ```rust,no_run
//! use yew_sidebar::{SidebarProps, MenuItem};
//! use yew::prelude::*;
//!
//! let menu_items = vec![
//!     MenuItem {
//!         icon: html! { /* Your icon HTML here */ },
//!         text: "Home",
//!         link: "/home",
//!         class: "your-menu-item-class",
//!         title: "Your Menu Title",
//!         submenus: vec![], // Nested MenuItem structures if needed
//!     },
//!     // Add more MenuItem structures as needed...
//! ];
//!
//! let sidebar_props = SidebarProps {
//!     fixed: false,
//!     sider_collapsed: false,
//!     title: "Your Sidebar Title",
//!     menu_items,
//!     // Customize other props as needed...
//!     // ...
//!     ..SidebarProps::default()
//! };
//!
//! let sidebar_component = html! {
//!     <Sidebar ..sidebar_props />
//! };
//! ```
//!

//! If you encounter any issues or have suggestions for improvements, feel free to contribute
//! to the [GitHub repository](https://github.com/next-rs/yew-sidebar). We appreciate your feedback
//! and involvement in making Yew Sidebar better!
