Placing the navigation menu

Can you treat the navigation pretty much like any other object and move it to where you want it on a page? I've created some shapes and pictures and text boxes below where the menu sits as it;s default position near the top of the page, and when I move it, it pushes the objects out of it's way. I tried sending these objects to the back with the arrange commands, but it doesn't seem to behave normally as other objects do. Is there something I'm missing here? I'd like to have it sitting on a colored background. Thanks!
