Quick Style Choose via button

[Sin City]

ok i've seen the "quick style chooser" edit which makes the drop down.... but can someone tell me how i'd go about setting up the same kind of quick style chooser, but by process of a button to be placed with "User CP, Home, FAQ" etc. buttons at the top of the forums that when clicked would make the list drop down like, for example, the search feature does?.... thanks in advance :smoke:
