[Plugin: NextGEN Gallery] Gallery Shows In Front Of Drop-Down Menu

Hello, I’m working on a new website for which I have both a drop-down menu and a NextGEN gallery slideshow on the home page. I would like to have the drop-down menu appear on top of the images…for some reason, the menu appears behind the gallery, and two of the options are only visible while the images are fading. I have tried to adjust this by placing it within a div and setting its z-index to a number lower than the z-index of the header, but no such luck. Does anyone have any solutions?

On testing.jakebinstein.com, hover your mouse over the “Collections” button on the menu, there should be three drop-downs, only one is visible until the picture fades though.

I can provide more information if it’s needed. Thank you!
