I may have been misunderstood, sorry for my bad English.

I dont want to "classic" megamenu, i have only categories and subcategoris. 

Now all of subcategories are only one line. I would like to change it 2 or 3 columns, so the overall width will be smaller as well.

I tried to add css class second and third levels from your documentation, but nothing helped to me.

"width-250

by default, width of item element in menu is the same as width of Menu title, but you can increase it if you add width-250 class. You can also add width-300 and width-200"

How to place subheadings and how to make custom full width mega menus is described in our video

Hi!

I made in main menu a vertical menu for my product categories.

I made some subcategories too.

But the sumbs print only one line.

How can i make smaller width for sub menus, and / or change the maximum columns number?

I tried to find your custom CSS classes (example i used it the first menu, you can see the screenshot) but i didnt find good solutions for submenus widht / columns problem in documentation.

i use latest WC + WP versions, and build full of site with gutenberg.

Thanks your support.
