Products
Liferay provides four product types out-of-the-box: Simple, Grouped, Virtual, and Diagram. Catalogs hold products with a default SKU at creation time. By default, all products are visible in a catalog and across all channels. However, you can control product visibility by determining channel or account eligibility. After creation, you can also assign multiple SKUs to each product to represent different variants.
See Product Configuration Reference for more information on how to configure a product.
