Hi,
I refer to the category of the product, the customer can find the category of the product in this template: https://prnt.sc/26ljg1s
But in this template, how does the customer find the category of the product: https://prnt.sc/26ljhl9
These categories are added by means of the Product category element in the Header builder: https://prnt.sc/26ljg1s
The menu you show is added by means of the Main menu in the header builder.
