# 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.

<div id="productsandservices" class="yuimenu"> <div class="bd"> <ul class="first-of-type"> <li class="yuimenuitem"> <a class="yuimenuitemlabel" href="#communication"> Communication </a> <!-- A submenu --> <div id="communication" class="yuimenu"> <div class="bd"> <ul> <!-- Items for the submenu go here --> </ul> </div> </div> </li> <li class="yuimenuitem"> <a class="yuimenuitemlabel" href="http://shopping.yahoo.com"> Shopping </a> <!-- A submenu --> <div id="shopping" class="yuimenu"> <div class="bd"> <ul> <!-- Items for the submenu go here --> </ul> </div> </div> </li> <li class="yuimenuitem"> <a class="yuimenuitemlabel" href="http://entertainment.yahoo.com"> Entertainment </a> <!-- A submenu --> <div id="entertainment" class="yuimenu"> <div class="bd"> <ul> <!-- Items for the submenu go here --> </ul> </div> </div> </li> <li class="yuimenuitem"> <a class="yuimenuitemlabel" href="#information"> Information </a> <!-- A submenu --> <div id="information" class="yuimenu"> <div class="bd"> <ul> <!-- Items for the submenu go here --> </ul> </div> </div> </li> </ul> </div> </div>

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.

/* Instantiate the menu and corresponding submenus. The first argument passed to the constructor is the id of the element in the DOM that represents 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 }); /* Call the "render" method with no arguments since the markup for this Menu instance is already exists in the page. */ oMenu.render();
