I'm building a (Drupal 7.5) site where I use mmenu (Mobile Sliding Menu) module to create the menu. When I click the trigger, the main menu items appears. Some of the main items have a submenu. When I click the trigger for those submenus, the submenu opens, so far so good.
When I then click another submenu trigger, that submenu opens, but the previously opened submenu stays open as well. What do I need to change to have only ever one submenu open at any one time (i.e. triggering a new submenu closes one that was opened before)? There is no setting for this in the mmenu configuration (drupal module), and no instructions on this on the mmenu website (http://mmenu.frebsite.nl).
Many thanks for any help on this.
