I have a question regarding flash. I am an intermediate flash user. Basically, I want a flash movie to expand like this homepage video, when the user clicks on the go button: http://www.vitsoe.com/en/gb

1. Is it possible to "expand" the borders of a flash animation in such a way, and if so, how do I set this up in flash?
2. Is it possible to have the drop-down menu displace the content below it on a html site? i.e. a 250-pixel high banner drops from the original flash piece, is it possible to have the rest of the page move down 250-pixels as well?

Any help would be immensely appreciated as I can't seem to find a straight forward flash tutorial to assist me.
