'#' items In the Menu don't bring up the sub-menu items.

Hi there,

Our client (bromsgrovewebmarketing.co.uk) is having issues with his site, when using a Surface tablet, using IE10.

The ‘#’ items In the Menu don’t bring up the sub-menu items.

Some people in forums are saying you can add:
aria-haspopup=”true”
To the # menu item, according to:

is there anything you can do please?

thank you
