I don’t understand. I add another first level menu. Simply duplicating. My other menus are presented full witdh. Unfortunataly, the new one is presented a default.
The other menu show: menu-item-design-full-width menu-mega-dropdown
The new one show: menu-item-design-default
I don’t see any difference anywhere I look in the dashboard. No custom css, nothing.
If yes, make sure you have not added to the ACCESSOIRES PRATIQUES sub-menu item in Appearance > Menu. When you add a sub-menu item, your mega-menu block does not show.
If it is not what you mean, please describe you actions step by step and purpose which you want to achieve.
When you arrange the menu by means of menu item, sub-menu item, it is not possible to make the drop-down full-width due to HTML structure. If you want a full-width menu you will need to create a mega menu block. Please read and follow the instructions: https://xtemos.com/docs/woodmart/create-menu-2/
