Forum:Show-Hide button

I've seen on Wikipedia a "show-hide" tab on the side of some headers (similar to the "dismiss" thing on the sitenotice about the fundraising on Wikimedia). Does anyone know how this works and what markup to use? I thought it was something to do with "NavHead" but that didn't work. I've searched Mediawiki.org and meta, but haven't come up with anything.

 * Read over Forum:ShowHide content. Dantman (Talk) 08:52, 24 January 2007 (UTC)
 * Hmm, thanks, should've read over the current topics. Do you know, if I put that js he's talking about into MediaWiki:COmmon.js, will it show up for everyone on the wiki?  Even unregistered users?  Scott ch 08:55, 24 January 2007 (UTC)
 * Actually, that's not a page. Isn't there a common js page in the MW namespace that will apply to all users, regardless of skin?  Scott ch 08:56, 24 January 2007 (UTC)
 * There isn't one yet. MediaWiki:Common.js is supported in a future version which we will upgrade to in a few weeks (I hope). Use MediaWiki:Monobook.js for now. --Splarka (talk) 10:14, 24 January 2007 (UTC)
