Creating a Menu with submenus from JavaScript

To create a Menu with no pre-existing markup on the page, call the Menu constructor (YAHOO.widget.Menu) passing the id of the Menu element to be created as the first argument.

Add items to a Menu instance via the addItem, insertItem, or addItems methods.

To add a submenu to a MenuItem via script, set the MenuItem instance's "submenu" configuration property to an object literal that specifies values for both the "id" and "itemdata" properties.

Finally, it is necessary to call the render method passing the id of, or reference to the element the Menu should be appended to.

/*
     Define an array of object literals, each containing 
     the configuration properties necessary to create a MenuItem and 
     its corresponding submenu.
*/
