Tricky flash menu

Hi all,

Am buildig a Flash site for someone. Action script isn’t a particular strong point of mine as I am just learning it as I go.

For his site, the guy wants a button menu like the one in the main site at [COLOR=#336699]http://www.boffi.com[/COLOR].

In other words, a menu where once a button is clicked, it will drop down a sub menu with more links. Then, if another main menu button is clicked then the first sub menu will close up and the new one would open. And so on.

I spoke to a friend who couldn’t really help me other than to say I would need to make movie clips of each movement and work it like that. He said I would need to use present and future variables (!?) to control the closing and opening of sub menus.

Does anyone have any ideas on this or could point to any tutorials or something similar. I have a bit of time (up until christmas) on my side to play around. I’m presuming it will be tricky.

Any help much appreciated!

Thanks, Ian.
