Ah OK ! Now i see where the problem is
Your screen shot gave me a clue. It only works correctly if the window rendering the page is open very wide, if one opens a window of what i would call “normal size” it fails to render correctly, and instead rolls the menus into an accordion drop down.
So this is not not helpful to us, can the parameters of the script that handles the menu be adjusted to work correctly in and more normal window ? If not we will have to drop this template and find something else.
here is what the page looks like to me, stock Safari 5.1.10 on OS X 10.6.8, it is the same for v6 and v7 up to OS X 10.9 (none of us run 10.10 yet)
