I have a navbar build with Twitter Bootstrap 3.1.1. When on an iPhone or iPad the dropdown menu hides behind the slider image. It has a position absolute and a z-index of 1000.
When on a desktop it goes well, it goes over de slider images.
If you go to http://sitegeregeld.nl/. You see that the dropdown menu disappears behind the slider on the homepage on an iPad and iPhone. I don't see a sollution.
What goes wrong?
