Hi all! I'm still struggling to understand how expanded/collapsed state of panels do work. I'm currently using a 2.4.30451 XE/XEM installation. Looking for macros controlling this state in macros.vm, I see: *** #macro(panelheader $title) #set($cookieName = "${context.user.replaceAll(':','')}_${panel}") #set($expanded = $xwiki.getUserPreferenceFromCookie($cookieName)) #if(!$expanded) #set($expanded = 'expanded') #end ## Note: We pass the Panel name as an HTML class attribute so that it's possible to style ## the Panels selectively using CSS. #set ($specialClassAttribute = "") #if ($paneldoc && $paneldoc != "") #set ($specialClassAttribute = $util.convertToAlphaNumeric($paneldoc.name)) #end <div class="panel $expanded $specialClassAttribute"> <h1 class="xwikipaneltitle" onclick="togglePanelVisibility(this.parentNode, '${cookieName}');">$title</h1> <div class="xwikipanelcontents"> #end *** This macro creates an expanded panel. By clicking the panel title, the system creates a cookie that stores her current state. But if I modify this macro and says... #if(!$expanded) #set($expanded = 'collapsed') #end No macro is created and panels are always collapsed when loaded and after relaoding.

Please, could you me understand why? Thank you so much!!! Ricardo -- Ricardo Rodríguez CTO eBioTIC. Life Sciences, Data Modeling and Information Management Systems _______________________________________________ users mailing list users(a)xwiki.org http://lists.xwiki.org/mailman/listinfo/users

But if I modify this macro and says... #if(!$expanded) #set($expanded = 'collapsed') #end No macro is created and panels are always collapsed when loaded and after relaoding. That is because 'collapsed' is used as a class name for the panel dom element and there is also a CSS rule which says that panels with 'collapsed' class name are being displayed as collapsed. So, the default logic is like this: 1) take the $expanded value from a cookie 2) set the panel dom element class name as being the value of $expanded 3) on loading the page, with the help of CSS, display the panel as being 'collapsed' or 'expanded', depending on the value of $expanded And in your case, this is the logic: 1) set the value of $expanded as being 'collapsed' 2) set the panel dom element class name as being the value of $expanded (which is 'collapsed') 3) on loading the page, with the help of CSS, display the panel as being 'collapsed', this being the value of $expanded I hope that this helps you understand the logic behind 'collapsed' and 'expanded' panels.

Please, Lockie, how to you get a collapsed panel at page loading time being later on controlled by a cookie? I mean, panel A appears collapsed when you access the site for the first time. From this moment onwards, a cookie will remember the preferences of each visitor.

Hello Ricardo and Lockie, If you want the initial value to be collapsed, but then you want cookies to work, what you have to do is to add a JavaScript function that will handle the initial cookie. The rationale is: 1. Check if a cookie exists for the current panel, on the client side 2. If there is no such cookie, toggle panel visibility This is the code of a panel: ## ## Get cookie ## ---------------------------------- #set($id = $util.generateRandomString(30)) #set($cookieName = "${xcontext.user}_${panel}") #set($panelCookie = $xwiki.getUserPreferenceFromCookie($cookieName)) ## ## Display panel ## ---------------------------------- #panelheader("Test") #panelfooter ## ## If there is no cookie set for the current panel, ## toggle panel visibility (since by default the panel is expanded) ## ----------------------------------------------------------------------------------------- #if("$!panelCookie" == '') #end This way, you don't need #set($expanded = 'collapsed') anymore. I hope this helps you both, Raluca.
