This example demonstrates how to create a multi-tiered menu using nothing but JavaScript.
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.
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.
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.
