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