Menus are unresponsive on mobile devices
I have been setting up the menu structure for a customer site. The menus all work fine using various desktop browsers. However, when I view these menus in something on a mobile platform–Safari or Chrome, for example–the menus do not work. The only link that works is the Home link. All submenu links do nothing. I have tested this situation with and without background images on the main menu items, and neither approach changes the behavior.
Please suggest the means to investigate this issue so that we can solve the situation. The initial structure of the site needs to be displayed to the client on Tuesday, so timely resolution would be very much appreciated.
