Hi! Following these lines in the panelheader macro un macros.vm... #macro(panelheader $title) #set($cookieName = "${context.user}_${panel}") #set($expanded = $xwiki.getUserPreferenceFromCookie($cookieName)) #if(!$expanded) #set($expanded = 'expanded') #end I understand that the default value, expanded, for XWiki panels is set there. This code says: 1. Set the name of the cookie that fixes the expanded/collapsed state for a given user and panel. 2. If this cookie exists and it has this preference set, it takes the value from it. 3. If fails to get the value from the cookie, set the value as 'expanded' Thus, all panels are shown expanded by default and, to the best of my understanding, setting: #set($expanded = 'collapsed') Must show all the panels closed. I'm not able to get this working. Please, where am I wrong? Thanks for your help! Ricardo -- Ricardo Rodríguez CTO eBioTIC. Life Sciences, Data Modeling and Information Management Systems
