I have a top-level menu item that on mouse-over “drops down” to view the second-level menu items, which works fine on e.g. laptop and ipad. The problem is when viewing the website on a smaller device (e.g. iphone 5). Then, when tapping the text of the top-level menu item, nothing happens. You have to tap the small downward-facing arrow to the right to get the drop-down. This is very frustrating since you expect that tapping anywhere on the menu item (either on text or arrow) should open the drop-down.
