Forum:Template not collapsing

I'm creating a navigational template in my sandbox, but it doesn't seem to be collapsing, can anyone lend a hand?

w:c:spyro:User:Semajdraehs/sandbox is where i'm creating it.

 * Should work now. I put some code in your wiki's MediaWiki:Common.js and MediaWiki:Common.cs for it to work.--Richardtalk 19:59, 29 April 2009 (UTC)
