Creating an "accordian" style effect

[crystalb24]

I'm trying to create a website with an accordian style effect on the tabs that rest on the right of the screen (like the effect used on this site -

http://www.danecook.com).

In Flex, it's an easy as adding a <mx:Accordian> tag (that only operates vertically as far as I can tell), but I'm still fairly new to Flash so I'm not sure how to get that effect here. Any ideas??
