/**
 * `` 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:
 *
 * ```
 * 
 * ```
 *
 * And then use [`items`](#/elements/vaadin-menu-bar#property-items) property to initialize the structure:
 *
 * ```
 * document.querySelector('vaadin-menu-bar').items = [{text: 'File'}, {text: 'Edit'}];
 * ```
 *
