How to add Advanced Rules for Category Weight Hide Shipping Method
Using Advanced Rules you can add multiple conditions related to category weight and then decide which shipping method you wish to apply as per the category’s overall weight.
Here, the category’s weight implies the total weight of products belonging to a specific category in the customer’s cart.
This rule works similar to the product-weight Advanced Rules, the only difference being that it works for a larger category (like accessories), instead of a few products (t-shirts).
