[xwiki-users] Dropdown Menu on Panel cut off

Hey, I'm trying to implement a vertical dropdown menu on one of my panels using CSS, but the extended popout submenu that appears on the side when the cursor hovers over the link gets cut off by the edge of the panel, so most of my submenu doesn't show up. This happens because the menu and submenu are part of the Panel document (SpaceLinks), so the extended submenu can't appear out of this panel document. Has anyone encountered this problem before and is there a simple solution? The source code for XWiki has this line of html for one of the already-existing dropdown menus of the Wiki: <div class="topmenuentry dropdownmenuentry hasIcon" onmouseover="showsubmenu(this);" onmouseout="hidesubmenu(this);" id="tmWiki"> Does the solution have something to do with onmouseover? I'm stumped. Any help would be greatly appreciated. Thanks, Felix
