jQuery UI Accordion

Overview

Make the selected elements Accordion widgets. Semantic requirements:

The markup of your accordion container needs pairs of headers and content panels:

<div id="accordion">
    <h3><a >First header</a></h3>
    <div>First content</div>
    <h3><a >Second header</a></h3>
    <div>Second content</div>
</div>

If you use a different element for the header, specify the header-option with an appropriate selector, eg. header: 'a.header'. The content element must be always next to its header.

If you have links inside the accordion content and use a-elements as headers, add a class to them and use that as the header, eg. header: 'a.header'.

Use activate(Number) to change the active content programmatically.

NOTE: If you want multiple sections open at once, don't use an accordion

An accordion doesn't allow more than one content panel to be open at the same time, and it takes a lot of effort to do that. If you are looking for a widget that allows more than one content panel to be open, don't use this. Usually it can be written with a few lines of jQuery instead, something like this:

jQuery(document).ready(function(){
	$('.accordion .head').click(function() {
		$(this).next().toggle();
		return false;
	}).next().hide();
});

Or animated:

jQuery(document).ready(function(){
	$('.accordion .head').click(function() {
		$(this).next().toggle('slow');
		return false;
	}).next().hide();
});

//setter
$( ".selector" ).accordion( "option", "active", 2 );
```
animated

```
$( ".selector" ).accordion({ animated: 'bounceslide' });
```
Get or set the animated option, after init.
```
//getter
var animated = $( ".selector" ).accordion( "option", "animated" );
//setter
$( ".selector" ).accordion( "option", "animated", 'bounceslide' );

autoHeight

Type:
Boolean

If set, the highest content part is used as height reference for all other parts. Provides more consistent animations.

//setter
$( ".selector" ).accordion( "option", "autoHeight", false );
```
clearStyle

Type:
Boolean
Default:
false

If set, clears height and overflow styles after finishing animations. This enables accordions to work with dynamic content. Won't work together with autoHeight.
Code examples
Initialize a accordion with the clearStyle option specified.
```
$( ".selector" ).accordion({ clearStyle: true });
```
Get or set the clearStyle option, after init.
```
//getter
var clearStyle = $( ".selector" ).accordion( "option", "clearStyle" );

var event = $( ".selector" ).accordion( "option", "event" );
//setter
$( ".selector" ).accordion( "option", "event", 'mouseover' );

fillSpace

Type:
Boolean
Default:
false

If set, the accordion completely fills the height of the parent element. Overrides autoheight.
Code examples
Initialize a accordion with the fillSpace option specified.
```
$( ".selector" ).accordion({ fillSpace: true });
```
Get or set the fillSpace option, after init.
```

Selector, jQuery
Default:
'> li > :first-child,> :not(li):even'

Selector for the header element.
Code examples
Initialize a accordion with the header option specified.
```

Object
Default:
{ 'header': 'ui-icon-triangle-1-e', 'headerSelected': 'ui-icon-triangle-1-s' }

Icons to use for headers. Icons may be specified for 'header' and 'headerSelected', and we recommend using the icons native to the jQuery UI CSS Framework manipulated by jQuery UI ThemeRoller

```
navigation

Type:
Boolean
Default:
false

If set, looks for the anchor that matches location.href and activates it. Great for href-based state-saving. Use navigationFilter to implement your own matcher.
Code examples
Initialize a accordion with the navigation option specified.
```
$( ".selector" ).accordion({ navigation: true });
```
Get or set the navigation option, after init.
```
//getter
var navigation = $( ".selector" ).accordion( "option", "navigation" );

Type:
accordioncreate

This event is triggered when accordion is created.
Code examples

Bind to the create event by type: accordioncreate.
```
$( ".selector" ).bind( "accordioncreate", function(event, ui) {
  ...
});
```

change

Type:: accordionchange

This event is triggered every time the accordion changes. If the accordion is animated, the event will be triggered upon completion of the animation; otherwise, it is triggered immediately.

$('.ui-accordion').bind('accordionchange', function(event, ui) {
  ui.newHeader // jQuery object, activated header
  ui.oldHeader // jQuery object, previous header
  ui.newContent // jQuery object, activated content
  ui.oldContent // jQuery object, previous content
});

Code examples

Supply a callback function to handle the change event as an init option.

$( ".selector" ).accordion({
   change: function(event, ui) { ... }
});

Bind to the change event by type: accordionchange.

$( ".selector" ).bind( "accordionchange", function(event, ui) {
  ...
});

changestart

Type:: accordionchangestart

This event is triggered every time the accordion starts to change.

$('.ui-accordion').bind('accordionchangestart', function(event, ui) {
  ui.newHeader // jQuery object, activated header
  ui.oldHeader // jQuery object, previous header
  ui.newContent // jQuery object, activated content
  ui.oldContent // jQuery object, previous content
});

Code examples

Supply a callback function to handle the changestart event as an init option.

$( ".selector" ).accordion({
   changestart: function(event, ui) { ... }
});

Bind to the changestart event by type: accordionchangestart.

$( ".selector" ).bind( "accordionchangestart", function(event, ui) {
  ...
});

destroy

Signature:
.accordion( "destroy" )

Remove the accordion functionality completely. This will return the element back to its pre-init state.
disable

Signature:
.accordion( "disable" )

Disable the accordion.
enable

Signature:
.accordion( "enable" )

Enable the accordion.
option

Signature:
.accordion( "option" , optionName , [value] )

Get or set any accordion option. If no value is specified, will act as a getter.
option

Signature:
.accordion( "option" , options )

Set multiple accordion options at once by providing an options object.
widget

Signature:
.accordion( "widget" )

Returns the .ui-accordion element.
activate

Signature:
.accordion( "activate" , index )

Activate a content part of the Accordion programmatically. The index can be a zero-indexed number to match the position of the header to close or a Selector matching an element. Pass false to close all (only possible with collapsible:true).
resize

Signature:
.accordion( "resize" )

Recompute heights of the accordion contents when using the fillSpace option and the container height changed. For example, when the container is a resizable, this method should be called by its resize-event.

The jQuery UI Accordion plugin uses the jQuery UI CSS Framework to style its look and feel, including colors and background textures. We recommend using the ThemeRoller tool to create and download custom themes that are easy to build and maintain.

If a deeper level of customization is needed, there are widget-specific classes referenced within the jquery.ui.accordion.css stylesheet that can be modified. These classes are highlighed in bold below.

Sample markup with jQuery UI CSS Framework classes

<div class="ui-accordion ui-widget ui-helper-reset">
  <h3 class="ui-accordion-header ui-helper-reset ui-state-active ui-corner-top">
    <span class="ui-icon ui-icon-triangle-1-s"/>
    <a >Section 1</a>
  </h3>
  <div class="ui-accordion-content ui-helper-reset ui-widget-content ui-corner-bottom ui-accordion-content-active">
    Section 1 content
  </div>
  <h3 class="ui-accordion-header ui-helper-reset ui-state-default ui-corner-all">
    <span class="ui-icon ui-icon-triangle-1-e"/>
    <a >Section 2</a>
  </h3>
  <div class="ui-accordion-content ui-helper-reset ui-widget-content ui-corner-bottom">
    Section 2 content
  </div>
  <h3 class="ui-accordion-header ui-helper-reset ui-state-default ui-corner-all">
    <span class="ui-icon ui-icon-triangle-1-e"/>
    <a >Section 3</a>
  </h3>
  <div class="ui-accordion-content ui-helper-reset ui-widget-content ui-corner-bottom">
    Section 3 content
  </div>
</div>

Note: This is a sample of markup generated by the accordion plugin, not markup you should use to create a accordion. The only markup needed for that is
<div>
   <h3><a >Section 1</a></h3>
   <div>
      Section 1 content
   </div>
   <h3><a >Section 2</a></h3>
   <div>
      Section 2 content
   </div>
   <h3><a >Section 3</a></h3>
   <div>
      Section 3 content
   </div>
</div>.
