A menu can be created from any valid markup as long as the elements have a strict parent/child relationship and each menu item has an anchor. The most commonly used element is the unordered list (<ul>):

<ul id="menu">
	<li><a href="#">Item 1</a></li>
	<li><a href="#">Item 2</a></li>
	<li><a href="#">Item 3</a>
		<ul>
			<li><a href="#">Item 3-1</a></li>
			<li><a href="#">Item 3-2</a></li>
			<li><a href="#">Item 3-3</a></li>
			<li><a href="#">Item 3-4</a></li>
			<li><a href="#">Item 3-5</a></li>
		</ul>
	</li>
	<li><a href="#">Item 4</a></li>
	<li><a href="#">Item 5</a></li>
</ul>

If you use a structure other than <ul>/<li>, including using the same element for the menu and the menu items, use the menus option to specify a way to differentiate the two elements, e.g., menus: "div.menuElement".

Any menu item can be disabled by adding the ui-state-disabled class to that element.

To add icons to the menu, include them in the markup:

<ul id="menu">
	<li><a href="#"><span class="ui-icon ui-icon-disk"></span>Save</a></li>
</ul>

Menu automatically adds the necessary padding to items without icons.

Keyboard interaction

• ENTER/SPACE: Invoke the focused menu item's action, which may be opening a submenu.
• UP: Move focus to the previous menu item.
• DOWN: Move focus to the next menu item.
• RIGHT: Open the submenu, if available.
• LEFT: Close the current submenu and move focus to the parent menu item. If not in a submenu, do nothing.
• ESCAPE: Close the current submenu and move focus to the parent menu item. If not in a submenu, do nothing.

Typing a letter moves focus to the first item whose title starts with that character. Repeating the same character cycles through matching items. Typing more characters within the one second timer matches those characters.

Disabled items can receive keyboard focus, but do not allow any other interaction.
