[xwiki-users] Panels

have a two questions about Panels 1) How can I make the panel default display "collapsed"? 2) Is there any logic in where you define the display of panels - in the admin - presentation ; attributes, show left panel = true, left panels, show right panel= true right panels - panel wizard, but although the setting is show left column - the admin, per space - panel wizard, per space What is the best place to learn understand panels, the do's and do not's? My problem is that am having difficulties predicting what will happen, some panels can be displayed in a certain space while not in another? Thx, Gerritjan
