Top Naviagtion Bar problems on Mobile: how to fold back / close again?

Hi,

is there a way that the auto nav bar on top (Atomic, Concrete 9.2.0) can be folded back (closed) after opening.
Whenever I open a navbar drawer on the mobile, I am unable to close it again. Instead of closing the page itself opens (the first item of the drop down navigation list)
Thanks already

@ong - not that I know of - I agree that would be a nice feature request. You can make that here.
