I set Nivo up on a page using a full screen CSS hamburger menu for mobile use. The menu is displayed under the Nivo slideshow instead of on top of it when clicked. Is there a fix or work around?

Probably your menu z-index is lower than the one of the slider. You can check that with your browser dev tools.

Thank you so much!! It was 2am after working all day and my brain overlooked the obvious. Can't thank you enough!
