Submenu not disappearing with anchor links on tablet

Hello there!

Our Mega Menu is composed of anchor links and it works correctly on desktop, but we have detected a problem on tablet that we don’t know how to solve… When trying to navigate through the anchors of a page, the submenu remains displayed and does not allow a correct navigation. How can we make it disappear when clicking on the link?

I add a demonstration video in this link: https://www.datacyl.com/ftp/video_tablet.zip (It is in spanish, but it shows clearly the issue)

Thank you very much for your attention
