Mobile Devices not working; Gallery + Menu Problems;

Hi,

i have some problems with the Mega Menu:
1. I can't open the menu on mobile devices (Toggle Button);
2. Mobile Devices: The blue menu is smaller than the grey background, why? (It works fine on my Desktop;)
2. I hid the toggle button. It works a little bit better, but if there are too many links there are some problems again; If there are "too many" links, it's overflowing the text;
3. I'm also using the JUX Gallery; If the Mega Menu "touches" the Gallery, the menu is behind the gallery.
