I had the same problem and found a light workaround that I used here a hover example
The Post Natal and Ante Natal options, when they freeze, cause a drop, but you may notice that they are NOT links. In my original model, they were links, but when I realized that this would not work on touch devices, I just turn them into triggers for drop-down boxes, and also put links inside the boxes. Thus, for you, your link “What we do” will not be a link, just a trigger for the drop-down menu, and then in the menu you can specify your link to the information “what we do”.
It’s also worth remembering that some touch devices, such as some iPads, don’t like hover states at all, if you find that the hover state doesn’t bring up a dropdown menu, then add 'onclick = "return true" to the list item in question. Usually this makes a hang state, like a click.
Hope this helps, what I wrote represents about 3 days of working on my reference library.
