Drop Up Footer Menu

I would like to have the menu items in the footer menu “drop up”.

Currently they are dropping down and can’t be seen.

Thanks,
Rod

I am surprised that I can’t find this option in the Mega Menu setup.

I am a newbee at CSS, so if possible … a simple CSS added to Mega Menu Settings would be great.
