Hello,
Thank you very much for choosing our theme and for contacting us.
The mobile menu is created and assigned in Appearance > Menu > Select menu and displayed by means of Mobile menu element in the Header Builder in the Mobile view. https://xtemos.com/docs/woodmart/header-builder/header-responsive-settings/
One and the same menu can be both Main and Mobile. Mobile menu does not support mega menu blocks as there is no space enough for mega blocks. Thus, it is necessary to create a clone of the Main menu without mega menu blocks. Mobile menu element has the option to show Category menu, which is created in Appearance > Menu. Mobile menu element also has the option to show or hide the search. http://prntscr.com/o8xl80
