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.

Each item in a Menu can contain a submenu which is set via its "submenu" configuration property. To add a submenu to an item, set the "submenu" property to an object literal containing an "id" property that represents the id for the submenu element and "itemdata" property that references an array of YAHOO.widget.MenuItem configuration properties to be used to create the items in the submenu.

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

var aItems = [

{   
        text: "Communication", 
        url: "http://communication.yahoo.com", 
        submenu: { 
            id: "communication", 
            itemdata: [ ... ] // Array of YAHOO.widget.MenuItem configuration properties
        } 
    },

{
        text: "Shopping", 
        url: "http://shopping.yahoo.com", 
        submenu: {
            id: "shopping", 
            itemdata: [ ... ] // Array of YAHOO.widget.MenuItem configuration properties
        } 
    },

{
        text: "Entertainment", 
        url: "http://entertainment.yahoo.com", 
        submenu: {
            id: "entertainment", 
            itemdata: [ ... ] // Array of YAHOO.widget.MenuItem configuration properties
        } 
    },

{ 
        text: "Information", 
        url: "#information", 
        submenu: {
            id: "information", 
            itemdata: [ .. ] // Array of YAHOO.widget.MenuItem configuration properties
        } 
    }

];

/*
     Instantiate the menu.  The first argument passed to the 
     constructor is the id of the DOM element to be created for the 
     menu; the second is an object literal representing a set of 
     configuration properties for the menu.
*/

var oMenu = new YAHOO.widget.Menu("productsandservices", { fixedcenter: true });

/*
    Add items to the menu by passing an array of object literals 
    (each of which represents a set of YAHOO.widget.MenuItem 
    configuration properties) to the "addItems" method.
*/

oMenu.addItems(aItems);

oMenu.showEvent.subscribe(function () {

this.focus();

});

/*
     Since this menu is built completely from script, call the "render" 
     method passing in the id of the DOM element that the menu's 
     root element should be appended to.
*/

oMenu.render("rendertarget");
