Menu falls out of frame

Hi there and thanks for a nice theme!

We are building on a site with many pages, based on theme Parabola. When checking the menus on a small screen I notice the menus fall out of frame in two different ways:

1. When the dropdown topmeny furthest to the right expands, longer subpage titles fall out of frame (to the right) and become unreadable. Only the first word or so is readable. A solution to this would perhaps be to make the subpage block fall down to the left instead of falling to the right if if does not fit on the screen.

2. On a dropdown topmenu with 20+ subpages expanding, the last subpage items will fall out of the bottom frame. You can not see the last subpages in the menu.

To make to theme 100% responsible it would be great if these two points can be discussed.
