jQuery Coda-Slider Expand-Collapse

I am using the Coda-Slider ( http://www.ndoherty.biz/demos/coda-slider/2.0/ ) for a project, and I would like to add a functionality:

So, clicking on the tabs at the top will slide from one panel to another.

I WANT: When you click on a tab that's already the current panel, I want the pannel (content box) to collapse.

I'开发者_JAVA技巧ve tried toggling classes, toggling slides.... nothing works...

Your help is appreciated!

Thanks!
