I have the same result on several pages of my site. I’ve tried deleting the shortcode and starting from scratch, with the same result. I’m on the latest version of WordPress. Sorry, I’m out of ideas.
Great, thanks Devin! Really interested in what they have to say. The 7th column is very important due to the nature of the content, so hoping there’s a work-around, even if it does involve editing the js.
I checked out the OP’s site above and it looks like they only got it working with 6 columns (at least it’s only 6 now).
Can I readdress this question and get a definitive answer on how to have 7 columns in a mega menu? It appears the the 7th is wrapped with js and adds a new UL tag…
