Overview documents for the Accordion plugin are incorrect.

[nmaves]

The following documentation is not valid.

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>

[Jörn Zaefferer]

The header element must have display:block, and for icons to work properly, the text must be wrapped in an ancor-element within the header element.

<div id="accordion">
	<h3><a href="#">Accordion Header 1</a></h3>
	<div>
		Accordion Content 1
	</div>
	<h3><a href="#">Accordion Header 2</a></h3>
	<div>
		Accordion Content 2
	</div>
	<h3><a href="#">Accordion Header 3</a></h3>
	<div>
		Accordion Content 3
	</div>
</div>
