Template:Hidden

Borrowed from The Other Wiki Documentation is located there. Reproduced here on July 27, 2012. Huge thanks to everyone over there who helped make this possible.
None of the below text is my own. It is more a place holder now than anything.. Change at will! :)

This template creates a dynamic navigation box using style sheet declarations in MediaWiki:Common.css and Javascript code in MediaWiki:Common.js. It displays the first parameter (the heading) with a [show] link on the right. If [show] is clicked by the user, the second parameter (the body) is displayed below the heading and the [show] link becomes [hide]. Clicking on [hide] then hides the body again and the [hide] link becomes [show] again.

The template does not provide an argument to designate the initial state of the show/hide control. In the nested case, show/hide controls in hidden content retain their state. There is no facility for collapse all or reveal all.
