Can the WhatsApp catalog show sizes and add-ons?

WhatsApp's catalog guide lists no size or add-on option. An item has a title, photos, price, sale price, description, link and product code, so list each size as its own item.

• Each item needs a unique title, at least one image and a country of origin. Everything else is optional.
• List one item per size, such as “Margherita, large”, each with its own price. Put add-ons in the description.
• Customers add items to a cart and send it to you as a message, so confirm add-ons in the chat.
• Prices can be added to a catalog only in certain countries.
