Superfish menu-fly out to right is cutoff. Can this be modified?

Here is my site:
 
In main horiz nav at top of page-go to "Client Resources"
Hover over "Client Portals". See how they open to right? Can I change this so this particular column flys out to the left?
 
Any guidance will be greatly appreciated!
