Why doesn't this menu toggle?
<p>On my site (<a href="http://test.tamarawobben.nl" rel="nofollow">http://test.tamarawobben.nl</a>) I use an accordion menu. When I choose the 2005 option and after that 2006, 2005 stays open though I was expecting it would close.</p>

<p>Can anyone give me a hint why this happens and how to fix it?</p>
