I mentioned the curriki tooltips issue because you noted performance issues in waiting for certain actions in curriki's navigation. Ludovic gave the example http://www.curriki.org/xwiki/bin/view/Coll_curriki/RefineyourSearchforLearn… note the extensive use of tooltips on each item as you "hover" over them in the navigation. IMHO, this is the reason for the perfomance issues: You noted: The point of my message was to point out that some of the widgetry you were looking at might perform differently in a different environment that doesn't burden the browser with as much work. Because of the particular tooltips approach used, JavaScript and the user's browser can be a potential performance bottleneck. A generalized imlementation of the navigation Ludovic pointed out might want to skip some of these performance bottlenecks, rather than replicating them. Or solve the issue by coming up with an incremental approach for tooltips. For example, using the "hover timeout" to fetch and compute the individual toolktip HTML for the item one's mouse is over, as opposed to having to precompute all the tooltips each time you expand a level in the navigation. Regarding your navigation needs, have you considered using (or modifying) Main.Dashboard or Main.SpaceIndex? The code snippet I put in the WebHome page of most spaces created on my site comes from Main.SpaceIndex, (usage example: /xwiki/bin/view/Main/SpaceIndex?space=Main ). Additionally, the code in Main.Dashboard indicates it can be used on a per-space basis: ## This dashboard can be used for both wikis (Main.WebHome) ## and spaces (*.WebHome). ## #set($isSpaceDashboard = false) #if($doc.space != "Main") #set($isSpaceDashboard = true) #end However, it sounds lke you're looking for something closer to Panels.Navigation, Panels.Spaces. or Panels.SpaceDocs ...
