Mobile mega menu column fix

Hi there,
I saw this post on the ThemeForest site:

msmith29063: “I’m using the mega menu with columns. Is there any way to get around the “Column 1” and “Column 2” submenu items for mobile? I’m not using column the headings on the desktop version. They’re hidden.”

Your response: “Sure we can provide you some custom CSS for that! just open a new ticket in our theme support forums with the above info along with the URL of your website and our support team will be glad to assist you with this.”

I have exactly the same issue. I don’t need the column headings in the mega menu. I’ve figured out how to “hide” them for desktop view but I need the same for mobile. Basically, I want all column headings hidden and all column items display in one list under the main top link.
