Category Combination Restrictions for WooCommerce

Category Combination Restrictions for WooCommerce lets you define pairs of product categories whose items can never appear in the cart at the same time. The restriction is bidirectional: if a product from Category A is in the cart, products from Category B cannot be added, and vice versa.

Features:

• Define unlimited category restriction pairs
• Fully bidirectional — one rule covers both directions
• Supports category hierarchies (subcategories inherit parent restrictions)
• Disabled add-to-cart buttons on shop and product pages with a clear explanation
• Option to show the explanation (for why a product can’t be added) with a clear message, or a tooltip
