Module menu_list 

MenuList — a themed vertical menu container with keyboard navigation.

MenuList is the dropdown panel used by MenuBar, MenuContext, and popover-style menus. It provides a themed surface (background, rounded border, drop shadow) and owns the full keyboard navigation stack: ArrowUp/Down moves focus, Enter activates, Escape bubbles to the enclosing overlay host, Home and End jump to the first/last enabled item. Type-ahead search jumps to the next item whose stripped label starts with the accumulated keystrokes (500 ms reset window by default).

Items are added with .item(widget) (any impl Widget, but typically a MenuItem); separators with .separator(). Conditional rows use .item_when(widget, visible_prop) — a hidden row collapses to zero height and is skipped by keyboard navigation. For very long lists (recent files, etc.) call .max_visible_items(n) to cap the panel height and wrap the content in a ScrollArea.

Safe-triangle hover gate. When a submenu item opens its child overlay, MenuList stamps a shared anchor so sibling items can skip their hover-switch while the cursor travels diagonally toward the submenu.

Accessibility

Role::Menu; each row is Role::MenuItem / Role::MenuItemCheckBox / Role::MenuItemRadio as declared by the item. Radio items in the same list auto-group via push_to_radio_group so AT announces “2 of 3”.

let _w = MenuList::new()
    .item(MenuItem::new(lit!("Cut")).on_activate_fn(|ctx| ctx.send_intent(Intent::new("app.cut"))))
    .item(MenuItem::new(lit!("Copy")).on_activate_fn(|ctx| ctx.send_intent(Intent::new("app.copy"))))
    .separator()
    .item(MenuItem::new(lit!("Paste")).on_activate_fn(|ctx| ctx.send_intent(Intent::new("app.paste"))));
