Second tier items in the drop down menu display to the right. Which is fine, but on a lower resolution monitor, especially with smaller browser window, the second tier items for nav links toward the right are partly hidden by the edge of the browser window. The user therefore has to resize the browser window and/or right scroll to see these items. The "easy" fix in principle is to make those second tier items appear to the left rather than the right. Is there a simple way to do this?

PS I hope you don't mind me posting sample images. Do they help?
