Auto close Nav (Source) in mobile view

One-page site, when viewed from a mobile, is it possible to return the menu to the initial situation once a link has been clicked?
Basically I have Nav (Source), in mobile view once the menu is open, tapping on one of the menu links (which point to page anchors), the menu remains open and you have to tap again to close the menu.
How can I make the menu close automatically after tapping?

Thanks Stuart

What was the solution out of interest?

Stuart, with the purchase of Versus, sent me an update of the script which improves recognition of the anchor-menu position and a script (as an exception) which improves the behavior of the menu, forcing close, perfect for the Versus demo.
Honestly the script updates fixed all the problems in the project caused by many stacks (which is really very complex).
Thanks again Stuart

Cool.
