Close submenu on click

Hi.

My site has sections in some pages that we link to in a dropdown megamenu with # to scroll to that section, but I can’t figure out how to close the menu on click.

Currently, for example, if I’m on the homepage and click on a link that scrolls to a section on the same page, the megamenu stays open – is there any way to close the megamenu on click?

Thanks in advance
