This may not be an option to fix, but I thought I’d ask the question.
Here is a screenshot of the mobile version of my menu.
As you can see there are many submenus. If I click on the actual arrow then the menu drops down, however, as the main menu item is just a blank custom link it does nothing but return to the current page.
Is there any fix available that means when a user clicks the actual menu item and not the down arrow it still opens up the submenu?
