/**
 * `<vaadin-menu-bar>` is a Web Component providing a set of horizontally stacked buttons offering
 * the user quick access to a consistent set of commands. Each button can toggle a submenu with
 * support for additional levels of nested menus.
 *
 * To create the menu bar, first add the component to the page:
 *
 * ```html
 * <vaadin-menu-bar></vaadin-menu-bar>
 * ```
 *
 * And then use [`items`](#/elements/vaadin-menu-bar#property-items) property to initialize the structure:
 *
 * ```js
 * document.querySelector('vaadin-menu-bar').items = [{text: 'File'}, {text: 'Edit'}];
 * ```
 *
 * ### Styling
 *
 * The following shadow DOM parts are exposed for styling:
 *
 * Part name         | Description
 * ------------------|----------------
 * `container`       | The container wrapping menu bar buttons.
 *
 * The following state attributes are available for styling:
 *
 * Attribute           | Description
 * --------------------|----------------------------------
 * `disabled`          | Set when the menu bar is disabled
 * `has-single-button` | Set when there is only one button visible
 *
 * See [Styling Components](https://vaadin.com/docs/latest/styling/styling-components) documentation.
 *
 * ### Internal components

 * - `<vaadin-menu-bar-list-box>` - has the same API as [`<vaadin-list-box>`](#/elements/vaadin-list-box).
 * - `<vaadin-menu-bar-submenu>` - has the same API as [`<vaadin-context-menu>`](#/elements/vaadin-context-menu).
 *
 * The `<vaadin-menu-bar-item>` sub-menu elements have the following additional state attributes
 * on top of the built-in `<vaadin-item>` state attributes:
 *
 * Attribute  | Description
 * ---------- |-------------
 * `expanded` | Expanded parent item.
