Hiya,
I’m struggling to get the multilevel function on the nav menu working.
It says: “edit your WordPress menu item to enable multilevel functionality” but I’m not sure how to do that. I’ve already got a cascade of sub items on my menu.
Many thanks in advance!
I’ve got the bricks builder 1.11.1.1 version.

On the Wordpress Menu editing page where you’ve setup your sub menus, there should be a checkbox labeled “Multilevel (Bricks)” under each top-level item. See screenshot below.
That is supposed to do the trick. However, I have not been able to get this to work myself so maybe there’s a bug? I realize your original post was more than a month ago. Did you ever get it working?
Also, throwing my hat in the ring. Doesn’t seem to work for my Wordpress menu’s either. Have set both the Multilevel to active in the Nav element, and in the Wordpress menu activated it for the top levels.
Anyone know what I’m missing or doing wrong? Or perhaps there is a bug?
