      public class MenuItem
      extends ListGridRecord
      implements HasClickHandlers

  Object specifying an item in a `Menu`. Each `MenuItem` can have a `title`, `icon`, `shortcut\n keys`, optional `submenu` and various other settings. To create a Menu, create a series of MenuItems and call `Menu.setItems()`.

  Alternatively, Menus support binding to a `DataSource`.

  As another option, here's a sample of a Menu in `Component XML`:

        <Menu>
           <items>
               <MenuItem title="item1" click="alert(1)"/>
               <MenuItem title="item2"/>
           </items>
        </Menu>
