Animation menu help

I’v been looking at the “Creating Drop-Down Menus” tutorial and wanted to make somthing similar to that one. The idè is that I want an door an when you hold your mouse over it and click the door will open alittle and the menu will pop out of the doorway. The problem is that I cant have onrollOver on my movie clip animation. So I was wondering how I could do this. Do I need to make several animations and then but them inside the button. So when I click it starts the open door animation and then more buttons come out? Hope you understand my problem and thanks in advance.
