Building a drop down menu like this (tutorials, help, examples)

Hi all,

Just wondering if anyone has any working drop menus like this one out there they could kindly share so I can deconstruct.

I am able to replicate the effect using tweens and basic AS but the process I have used involves hitareas being place all around the outside of the menus to get them to slide back in when I rolloff the menu (and onto the hit areas). They thing works but is quite ugly and makes the space unneath these hit areas comprimised.

Hopefully someone has a bit more of an intelligent design using more AS without losing the smoothness of the animation I could take a look at.

If anyone could assist would be great
