Joomshopping Addons: Exclude attribute for attribute value

The customer cannot pick an incompatible combination — once "Red" is selected, the "Size XXL" option that does not exist in red disappears from the list automatically instead of causing an error at the checkout.

Features

• For every attribute value the administrator defines the list of values of other attributes that become unavailable when it is selected ("Colour: red" → hide "Size: XXL", for example)
• Two modes are supported: hide the attribute value or hide the whole attribute if it has no allowed values left
• The rules are applied both on the product page (dropdown/radio buttons) and when adding to the cart — excluded attributes are removed from the cart data automatically (onBeforeAddProductToCart, onBeforeSaveNewProductToCartBPC)
• The exclusion setup is stored as a serialised array in the attribute value field — the rules are visible and editable right in the attribute value form in the backend
• ⚠️ Does not work when the JoomShopping option "First attribute value is empty: Yes" is enabled
