Thread:Project:Support desk/Sidebar Dorpdown question

Hello,

I searched this MediaWiki and the FAQ but couldn't find what I was looking for. So I was hoping someone over here could help me.

To start, the information of the wiki the question is about; MediaWiki: 1.11.2 PHP: 5.1.6 (apache2handler) MySQL: 5.0.77 I cannot provide a link, since this wiki is for my work and I'm not allowed to share the link, though I don't think/hope it's necessary for my question.

My question is this: Since a shortwhile, wikipedia (and this wiki as well) has dorpdown (?) menu's in the sidebar. That when you click on it, it shows/hides things. Now I would be very interested in implementing this for the wiki of my work. The problem is, I can't find how to do this. Is it because our MediaWiki is too old? Or am I not searching wel even.

I hope someone can help me with this, and I hope I explained it correctly, English is not my native language, so I don't know precisely what everything is called.
