Menu items double if I use the megamenu feature.

Hi,

That means the menu items also have submenus, they are visible on desktop as well -> https://prnt.sc/rPsZWwQ7dk9u It’s a common mistake when using megamenus.

The important thing to keep in mind, is that the menu item for which you activate the megamenu should not have submenus.

So for example these menu items can have megamenus -> https://prnt.sc/n4Q5mf4IsNv6
This one should not have a megamenu because it has submenus -> https://prnt.sc/zMN2nBqkcz5P

A megamenu already displays the subcategories of the category you select when you enable it, so it’s not necessary to also add the subcategories as submenus, because if you do they will be displayed twice -> https://prnt.sc/vYe9ruzmjcgs

I suggest removing the submenus from below the menu items that are megamenus -> https://prnt.sc/SBKPYKLg0gFO Then the issue should be solved.

Let me know if you have any questions or if there are other issues.

Thank you!

From what I see you have no menus in that language. Menus can be translated or created for each language. I suggest checking this guide -> https://wpml.org/documentation/getting-started-guide/translating-menus/

Thank you!
