Looking for sliding menu tutorial [renamed]


i need to realize some sliding menus. such as seen on: http://www.gooq.de/. that one at the bottom.

those who slide out and are active and shown as long as your mouse don’t leave their shapes. and then moving backwards. i’m searching my arse off but can’t find any hints. i don’t even know what they’re called. :h:

could you give me some names or links to tutorials please?

thanks a lot!
