Slider is hindering my drop down menus on mobile device

I have responsive slider on my site. The slider sits just below my drop down menu from my nav bar. When you click on the drop down menu to select an item, it works fine on a computer. But when you try and do the same on a mobile device, whichever one of the drop downs you click on you end up linking to the slider. How do I stop this from happening?

Thanks
