Close fullscreen overlay-nav when click menu-items

This plug-in is great, its very easy to modify and suit to your needs. I have added logo images and Font-Awesome Icons to both my MegaMenu and Overlay-nav menu. With that being said I wanted to add some simple functions to the Overlay-nav menu and I was wondering if anyone could help.

situation 1: I would like the menu to close shortly after menu-items are clicked.

situation 2: I would also like the menu to close when clicking anything thats not a menu-item.

Thank you.
