Thread:Project:Support desk/Collapsible Sections (ie: like Wikipedia:NavFrame)

Hello. I've done a significant amount of searching in the techincal help and support areas and yet cannot find the method to what I would like to do ...

I would like to create MediaWiki pages which allow entire sub-sections to be collapsible. This would be similar to the collapsible table but extended to sub-sections and sections. An example of this is on Wikipedia.

Wikipedia example of collapsible sections (ie. NavFrame show/hide functionality): w:en:Wikipedia:NavFrame

Existing Collapsible Table Extension (is this extendable to more than just tables?): Manual:Collapsible tables

My platform: MediaWiki v1.15.1 PHP 5.2.6 (apache2handler) MySQL 5.0.37

Webpage not available as it is on my intranet.
