Mobile Menu only category’s

Hi,

If I visit the website on my mobile and I open the menu I need to click on category’s to show the main menu.
I know how to put it off in the settings but then I don’t have a menu at all.
I would like to have the normal menu on my mobile and not at te category’s.
I can’t find where I can select my main menu in the mobile version I only see this option at category’s.

Thank you for helping me out.

Kind regards,

Melissa
