submenu elements going off screen

Hello,

I have a menu which has a couple of submenus. It seems that the submenus always opens to the right of the parent, which takes the submenu/s off-screen and is making them not visible and inaccessible.

Please advice on how to resolve this issues.

You can see the problem on my site http://www.velevadvisors.com. Check the “Client Center” menu item

Thanks,
Jivko
