Er, the best thing I can think of is the Wikipedia Navigation Dropdown Frame thing. Here's the code:
<div class="NavHead" style="WHATEVER DIV STYLE OPTIONS YOU WANT">TITLE OF THE BOX</div>
<div class="NavContent" style="WHATEVER DIV STYLE OPTIONS YOU WANT; display: none">
TEXT WHICH IS SHOWN AND HIDDEN
While this doesn't do exactly what you want this is the closest you can get, I think, without asking an admin to add bits of code to various files. With a bit of mangling you can probably get this to do what you want, almost. - 15:33 19 MaySirFSt. (QotFBFFNotM)YTTETalk!Read!Sign!Whore!CMC!Pee!
The keyword being almost. But, this is indeed what I wanted, thanks! VGD>=3 18:06, 19 May 2008 (UTC)
