Now I want to have the following. If the user is on Page 1 (or on a subpage) and opens the menu, then the subnavigation should be open and show the subpages. This should only happen on the mobile version (because most people don’t know, that they have to click on the arrow to open the submenu).
I’ve deactivated it. Now it’s active again. Here is the problem. I click on a 1st level menu item and the submenu keeps open. Now I click on a submenu item (2nd level) and the submenu disappears. I am talking about the mobile version.
