When I add a new item to menu, and put it under a Mega Menu item, it shows the checkbox “This column should start a new row”. I save the menu and website works fine.
But after save, when I edit the menu again, this checkbox disappears.
Please help with this issue. I need Mega Menu rows.
I hope you are well today and thank you for your question.
It’s Unyson plugin issue caused by WordPress core as described on the following page.
Thanks for the link. I have checked the information and it seems that it was fixed for WP 4.5 and later, but I still have this issue.
If you can test on your side to confirm the bug. If so, maybe you, as a theme developer, can report it to Unyson.
