public class MenuItem
extends ListGridRecord
implements HasClickHandlers

Menu items are specified are object literals, not class instances. For example, when developing in JavaScript, a typical initialization block for a Menu would look like this:

  Menu.create({
      data: [
          {title: "item1", click: "alert(1)"},
          {title: "item2"}
      ]
  });
  

And in XML:

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