Struct SettingsList 

pub struct SettingsList { /* private fields */ }

A scrollable list of toggleable settings rendered as checkboxes.

Each item is a (name, value) pair where value is true for checked [x] and false for unchecked [ ]. Items can be toggled with Enter or Space, and an optional on_change callback is fired on every toggle.

pub fn new(items: Vec<(String, bool)>) -> Self
