Forum:Collapsible sidebar

Does anyone know what manipulates the collapsible sidebar in Monobook? I was under the impression that "portlet"/"pbody" element would do the job, but it's not really. Compare the following sidebars in Halo Fan Fiction Wiki (collapsible) and Dead Space (not collapsible). Maybe some specific mediawiki page that I need to create/add/change? — subtank  ( 7alk ) 12:02, September 11, 2011 (UTC)

 * Have you looked at their MediaWiki:Monobook.js? — Sovq 11:46, September 13, 2011 (UTC)
