I'd like to place an accordion within a collapsible panel to be able to let the whole accordion dissappear at once... but somehow the accordion is not displayed below the CollapsiblePanel's header but on the right side of it! Does anybody know if this works in general? Or is there another way to make a accordion disappear and reappear?

 thanks, luke

Hi Luke,

You can add a Panel inside your CollapsiblePanelExtender and  put your Accordion inside the Panel. Now you can use Javascript to make it show or hide.   For example :   $get("<%=Panel1.ClientID%>").style.display = 'none'; or $get("<%=Panel1.ClientID%>").style.display = '';

Hope this help.

Best regards,

Jonathan
