Thread:Project:Support desk/Navbox not working 100%

I am working on a Wiki and trying to get the Navbox operating. I am very close example navbox

Most of the navbox displays correctly (show/hide, odd/even striping, table heading colors), except my lists are vertical. Also my groups headings are not picking up the table heading background color like it does in the Wikipedia navbox.

Installed SW


 * MediaWiki: 1.22.2
 * PHP: 5.3.10-1ubuntu3.12 (cgi-fcgi)
 * MySQL: 5.5.37-0ubuntu0.12.04.1-log

We don't have Lua or Tidy installed, so I used the version recommended at http://en.wikipedia.org/wiki/Wikipedia:WikiProject_Transwiki/Template:Navbox (and the {navbar} over there as well). I don't have server side access, but I did copy the CSS (MediaWiki:Common.css) and script (MediaWiki:Common.js). I tried the ones from MediaWiki first then Wikipedia (not sure if they were the same), but both had the same result. I copied the navbox/doc subpage, so I know the formatting is correct. I copied {Flatlist} to our Wiki just in case it was required, and it is working fine, but the {navbox} is still vertical. I can see the .navbar and .hlist entries in the Common.css files I copied, so I am not sure what else I missed.

I am going to start creating some custom templates using the .hlist styles to see if I can determine what is not working from the CSS.

Any pointers or suggestions would be greatly appreciated.
