Thread:Project:Support desk/Editing Left Navigation - adding drop downs and new sections

Hello,

I'm not able to find anywhere on this site that talks about how to change the links in the left navigation or how to add drop down links like are shown on the mediawiki page.

I've seen the TreeandMenu extension and that's not what I'm looking for. I'd like navigation just like how MediaWiki has...is there an extension for that?

Thank you
