Menu Widgetversion added: 1.9

Description: Themeable menu with mouse and keyboard interactions for navigation.

QuickNavExamples

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.

Dependencies

Additional Notes:

  • This widget requires some functional CSS, otherwise it won't work. If you build a custom theme, use the widget's specific CSS file as a starting point.

Options

disabledType: Boolean

Default: false
Disables the menu if set to true.
Code examples:

Initialize the menu with the disabled option specified:

1
$( ".selector" ).menu({ disabled: true });

Get or set the disabled option, after initialization:

1
2
3
4
5
// getter
var disabled = $( ".selector" ).menu( "option", "disabled" );
// setter
$( ".selector" ).menu( "option", "disabled", true );

iconsType: Object

Default: { submenu: "ui-icon-carat-1-e" }
Icons to use for submenus, matching an icon defined by the jQuery UI CSS Framework.
  • submenu (string, default: "ui-icon-carat-1-e")
Code examples:

Initialize the menu with the icons option specified:

1
$( ".selector" ).menu({ icons: { submenu: "ui-icon-circle-triangle-e" } });

Get or set the icons option, after initialization:

1
2
3
4
5
// getter
var icons = $( ".selector" ).menu( "option", "icons" );
// setter
$( ".selector" ).menu( "option", "icons", { submenu: "ui-icon-circle-triangle-e" } );

menusType: String

Default: "ul"
Selector for the elements that serve as the menu container, including sub-menus.
Code examples:

Initialize the menu with the menus option specified:

1
$( ".selector" ).menu({ menus: "div" });

Get or set the menus option, after initialization:

1
2
3
4
5
// getter
var menus = $( ".selector" ).menu( "option", "menus" );
// setter
$( ".selector" ).menu( "option", "menus", "div" );

positionType: Object

Default: { my: "left top", at: "right top" }
Identifies the position of submenus in relation to the associated parent menu item. The of option defaults to the parent menu item, but you can specify another element to position against. You can refer to the jQuery UI Position utility for more details about the various options.
Code examples:

Initialize the menu with the position option specified:

1
$( ".selector" ).menu({ position: { my: "left top", at: "right-5 top+5" } });

Get or set the position option, after initialization:

1

$( ".selector" ).menu( "option", "position", { my: "left top", at: "right-5 top+5" } );

roleType: String

Default: "menu"
Customize the ARIA roles used for the menu and menu items. The default uses "menuitem" for items. Setting the role option to "listbox" will use "option" for items. If set to null, no roles will be set, which is useful if the menu is being controlled by another element that is maintaining focus.
Code examples:

Initialize the menu with the role option specified:

1
$( ".selector" ).menu({ role: null });

Get or set the role option, after initialization:

1
2
3
4
5
// getter
var role = $( ".selector" ).menu( "option", "role" );
// setter
$( ".selector" ).menu( "option", "role", null );
