How is this navigation done?

How is this navigation done on Yahoo.com ? The tabs on the right side. Hover over the Horiscopes tab and the section drops down. I tried to look at the javascript but there is so much code I can't make sense of it. http://www.yahoo.com/

Something like this:

or this:

To be honest, the whole opening div is an effect that will require JS - MooFX does it pretty well.

Ther'es a lot going on there. 1st off, there's show/hide script onmouseover of each tab, but there's also a motion script moving the divs. Very complex
