Mobile menu # link

Hi – great theme! I’m having a problem with the mobile menu though. I have a menu item that just has a “#” link because it’s a trigger for a jQuery slidedown login form. Works fine in desktop view, but in mobile view the “#” link doesn’t hide the menu and the login form is hidden behind the menu. How can I get the menu to hide itself when the user clicks the “#” link?

Thanks for your help!
