Issue: submenu hidden by central block content?

I am using a slideshow on my central block content, but now my submenu appears hidden by the slideshow…

I thought of solving this using z-index but where am I going to set the z-index for the submenu? Maybe there is a better, easier solution…

any suggestions?
