Select mega menu does not appear in main menu item

Hi, I’ve installed Dunamis theme on our website but I can’t link the created croma mega-menu the to wordpress Main Menu.
Even if “Select Mega-menu part” is checked in the screen options it does not show up in the main menu item.

Im getting the same problem, any answer here?

Just upgrade your theme and the croma plugin

Where is the upgrade for the theme and Croma plugin? The developer stopped responding to all posts/comments/support over a year ago.

It looks like that item is no longer supported by the author, which they have indicated on their support page.

Did anyone ever get mega menus working again on this theme?
