Hi


I am wondering how can i create this effect.
I know some of it is done with mootools, but not sure what else is being used.

It is on the left navigation bar:

Where it says new featured and color variations.

I like how the color changes on the mouse overing, and the expandable sub-menu.

Let me know of any links or anything.


Thanks,
Chris
