Make the selected elements Accordion widgets. Semantic requirements:
The markup of your accordion container needs pairs of headers and content panels. By default, the header elements are anchors, assuming the following structure:
<div id="accordion">
<a href="#">First header</a>
<div>First content</div>
<a href="#">Second header</a>
<div>Second content</div>
</div>
If you use a different element for the header, specify the header-option with an appropriate selector, eg. header: 'h3'. 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.
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();
});
$("#accordion").accordion();

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
});
change event as an init option.
$('.selector').accordion({
change: function(event, ui) { ... }
});change event by type: accordionchange.
$('.selector').bind('accordionchange', function(event, ui) {
...
});
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
});
changestart event as an init option.
$('.selector').accordion({
changestart: function(event, ui) { ... }
});changestart event by type: accordionchangestart.
$('.selector').bind('accordionchangestart', function(event, ui) {
...
});Remove the accordion functionality completely. This will return the element back to its pre-init state.
Disable the accordion.
Enable the accordion.
Get or set any accordion option. If no value is specified, will act as a getter.
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).
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 ui.accordion.css stylesheet that can be modified. These classes are highlighed in bold below.
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 href="#">Section 1</a></h3>
<div>
Section 1 content
</div>
<h3><a href="#">Section 2</a></h3>
<div>
Section 2 content
</div>
<h3><a href="#">Section 3</a></h3>
<div>
Section 3 content
</div>
</div>.
