Struct CustomScrollbar 

pub struct CustomScrollbar<'a> { /* private fields */ }

Custom scrollbar widget for markdown navigation.

Shows scroll position using block characters with accurate tracking. Supports click-to-scroll and drag interactions.

This is a UI-only widget that receives &ScrollState for state access. State mutations happen through ScrollState methods, not here.

Example

use ratatui_toolkit::markdown_widget::state::scroll::ScrollState;

let scroll_state = ScrollState::default();
let scrollbar = CustomScrollbar::new(&scroll_state)
    .config(ScrollbarConfig::default())
    .show_percentage(true);
