Header and menu bar

[Joao61]

So i'm a civil engineer trying to use the va3c viewer in my master thesis with a website that incorporates a model viewer for better interaction between the structural engineer and the engineer onsite.

I got the viewer to work, but i can't include my php header and menu bar properly. All the elements of the header and menu aren't selectable, and to select an element of the building model, i have to click above it, the height of the header and menu bar to be exact.

1. Is it possible to include the header and menu bar in the va3c viewer?
2. Is there a way to separate the viewer from the header and menu from the viewer so that they don't afect one another?
