Menu Family: Multi-tiered Menu From Markup

This example demonstrates how to create a multi-tiered menu using existing markup on the page.

Note: By default clicking outside of a Menu instance will hide it. Additionally, MenuItem instances without a submenu or a URL to navigate to will hide their parent Menu instance when clicked. Click the "Show Menu" button below to make the Menu instance visible if it is hidden.

Creating a Menu with submenus from existing markup

The markup for a Menu control follows that of YAHOO.widget.Module, with its body element (<div class="bd">) containing a list element (<ul>).

Each item in a Menu is represented by a list item element (<li class="yuimenuitem">), each of which has a label (<a class="yuimenuitemlabel">) that can contain plain text or HTML.

In addition to a label, each MenuItem instance can also contain a submenu. To add a submenu via markup, simply nest the Menu markup inside the (<li class="yuimenuitem">) element representing a MenuItem instance.

To instantiate a Menu hierarchy based on existing HTML, pass the id of its corresponding root HTML element (in this case "productsandservices") to the Menu constructor (YAHOO.widget.Menu) then call the render method with no arguments. There is no need to instantiate and render submenus; as a convenience all submenus are automatically instantiated and rendered with the root Menu.
