I am having an issue with my navbar built using Twitter Bootstrap 3.1.1. On iPhones and iPads, the dropdown menu is hiding behind the slider image. It is set to position absolute and has a z-index of 1000.
Strangely, on desktop screens, everything works fine and the dropdown menu appears above the slider images.
Upon visiting , you can see that the dropdown menu disappears behind the slider on the homepage when viewed on an iPad or iPhone. I have not been able to find a solution to this problem.
What could be causing this issue?
