Hello friend.
It really hidden the products of the specific category in the shop page, thank you very much!

There is a way to hide it from the "father category" too?
Example:
Shop > Others > Hookahs

I want to hide "Hookahs" products from anywhere in the shop, except for its own category, but, it still appearing in the "Others" category.
I want "Hookahs" products only appears in "Hookahs" category.
I need to make a single category with age restriction, after hiding the items I will put a age verification plugin only in this category.
Or, if you have a better idea will be very welcome!
Thank you again.
