I need to add a visual tag/flag to all the products on a site that are in the category "free shipping".
You can see what I mean by looking at the M1 version of the site: https://monstergardens.com/products.html
I'm not at all familiar with how to write code to target the products that are in a specific category. If someone could help me figure that out, I'd really appreciate it.
The dev site for the M2 version is http://m2mg.gravitateframework.com/sm_market/
