Next, define an array of MenuItem configuration properties. Add a submenu to a MenuItem by setting
the MenuItem instance's "submenu"
configuration property to an object literal that specifies values for both the "id" and
"itemdata" properties. The "id" property specifies the id of the Menu to be created, while the
"itemdata" property accepts an array of MenuItem configuration properties, each of which is used to
configure the individual items in the Menu. Once defined, pass the array of MenuItem configuration
properties to the
addItems method of Menu.
Finally, it is necessary to call the
render method passing the id of, or reference to
the element the Menu should be appended to. Just as with creating a Menu hierarchy via existing
HTML, it is only necessary to instantiate and render the root Menu as each submenu is automatically
instantiated and rendered with the root Menu as a convenience.
