I used the following plugin for joomla: http://extensions.joomla.org/extensions/structure-a-navigation/menu-systems/drop-a-tab-menus/6731
This module simply combines superfish with the main menu and automates the setup configuration. I configured it so it appears vertically (accordion). It looks very nice and works fine. Except for one small detail. If somebody clicks on a sub-menu and the page changes to that item. Then the whole menu "collapses again" ("accordion closes"). If you hover along the menu path you can see that the current item is correctly highlighted, however when you move the mouse away the accordion closes Is there a way so that the accordion stays open with current item highlighted? Thank you very much again for your time and help in advance!
