Thread:Project:Support desk/Sidebar

I want my system manager to provide me with the possibility to have a sidebar with expandable/collapsable items. Exactly the type of sidebar which is implemented in this wiki. Ex: When I click Support, I can display sub items such as User help, technical manual, etc.

I could not find a solution that I'm sure that's the right one to propose to my Sys Mgr. What I found is that MediaWik version should be 1.17 with the Vector extension installed. Am I right or is there another way to meet this goal ?

Thanks, Philippe
