Menu Control Help!

Could someone point me in the direction of a tutorial that will allow me to control my menu. I have a two boxes, one on top of the other, when a person moves there mouse over, the box in the back rises upwards like a piece of toaste coming out of a toaster. The animation works fine but when setup in a menu system, I would like the toaster piece to stay when clicked and when another menu button is pressed to disappear to indicate which section the site visitor is at. thanks for any help you can offer.
