# llimphi-widget-menubar

An app's main menu bar.

Every Llimphi app declares an `app_bus::AppMenu` (File / Edit / View / Help …)
and mounts it in-window with this widget. It is the twin of `launcher_llimphi`'s
global bar, but it lives **inside** the app's window — for apps that run
standalone rather than under the launcher shell.

Stateless, Llimphi style: the host's `Model` carries which root menu is open
(`Option<usize>`); the widget flattens the `AppMenu` and emits a `Msg` on each
interaction.

Two entry points:

- `menubar_view` → the row of titles, for the top of `App::view`.
- `menubar_overlay` → the open menu's dropdown, for `App::view_overlay` (returns
  `None` when nothing is open).

Each item's `command` is the id the app understands (convention `menu.<verb>`,
see `app_bus::AppMenu::standard`); the widget bounces it back through
`on_command`.
