Thread:Project:Support desk/Pull down (?? menu : HowTo

Hi All@Mediawiki,

I'm trying to find how to modify the SideBar to have a "pull-down" menu (not sure it's the right name !), like the one @www.mediawiki.org

Here is a screen shoot circled here : http://trouspinette.free.fr/ZUNE/SideBar_Mediawiki_Triangle.jpg

Many thanks a lot for help :-)

NB : I'm not able to give the Mediawiki's URL, server is not reachable from the Internet.

Regards
