Tabs Widgetversion added: 1.0
Description: A single content area with multiple panels, each associated with a header in a list.
Tabs are generally used to break content into multiple sections that can be swapped to save space, much like an accordion.
Tabs have a particular set of markup that must be used in order for them to work properly:
- The tabs themselves must be in either an ordered (
<ol>
) or unordered (<ul>
) list - Each tab "title" must be inside of a list item (
<li>
) and wrapped by an anchor (<a>
) with anhref
attribute - Each tab panel may be any valid element but it must have an id which corresponds to the hash in the anchor of the associated tab.
The content for each tab panel can be defined in-page or can be loaded via Ajax; both are handled automatically based on the href
of the anchor associated with the tab. By default tabs are activated on click, but the events can be changed to hover via the event
option.
Below is some sample markup:

Theming
The tabs widget uses the jQuery UI CSS framework to style its look and feel. If tabs specific styling is needed, the following CSS class names can be used:
-
ui-tabs
: The outer container of the tabs. This element will additionally have a class ofui-tabs-collapsible
when thecollapsible
option is set.-
ui-tabs-nav
: The list of tabs.- The active list item in the nav will have a
ui-tabs-active
class. Any list item whose associated content is loading via an Ajax call will have aui-tabs-loading
class.-
ui-tabs-anchor
: The anchors used to switch panels.
-
- The active list item in the nav will have a
-
ui-tabs-panel
: The panels associated with the tabs. Only the panel whose corresponding tab is active will be visible.
-
Dependencies
- UI Core
- Widget Factory
-
Effects Core (optional; for use with the

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.

Events
activate( event, ui )Type: tabsactivate
Triggered after a tab has been activated (after animation completes). If the tabs were previously collapsed, ui.oldTab
and ui.oldPanel
will be empty jQuery objects. If the tabs are collapsing, ui.newTab
and ui.newPanel
will be empty jQuery objects.
activate
event is only fired on tab activation, it is not fired for the initial tab when the tabs widget is created. If you need a hook for widget creation use the create
event.Initialize the tabs with the activate callback specified:

Bind an event listener to the tabsbeforeactivate event:

beforeLoad( event, ui )Type: tabsbeforeload
Triggered when a remote tab is about to be loaded, after the beforeActivate
event. Can be canceled to prevent the tab panel from loading content; though the panel will still be activated. This event is triggered just before the Ajax request is made, so modifications can be made to ui.jqXHR
and ui.ajaxSettings
.
Note: Although ui.ajaxSettings
is provided and can be modified, some of these properties have already been processed by jQuery. For example, prefilters have been applied, data
has been processed, and type
has been determined. The beforeLoad
event occurs at the same time, and therefore has the same restrictions, as the beforeSend
callback from jQuery.ajax()
.
