Thread:Project:Support desk/Getting Collapse to work

I have two Wiki's,
 * MainDomain > everythingfoodanddrink.org


 * SubDomain > MyWiki.org


 * MediaWiki 1.17.0
 * PHP 	   5.2.17 (cgi-fcgi)
 * MySQL 	   5.1.52

My newest challenge is "Collapse". I helped build another little farm, before starting my own here and had the same difficulties. I have ( I think ) all the needed templates, the one I'm using to test with is and  and I do have. I use some navboxes on my site such as this one Template:ProjectNav, these are the reason I'd like to have them Collapsible but, I can now use the box alone to encase large threads and so on.

As far as .js and .css I have everything I have come across I think. I have a gut feeling this is a common issue and maybe a secret key no one thinks of. If anyone has a couple minutes and can scan through, maybe something obvious to you. Any and all help or thoughts will be greatly appreciated.

While posting this question I found this Nested collapsible tables does this have anything to do with my problem ? I notice en-WP does not have a page MediaWiki:Navigation.js or is this page just for Wikiversity ?
