OpenCart Multi Vendor: Restricting Number of Categories for Single Product

OpenCart Multi Vendor allows administrators to manage multiple vendors selling on a single platform. One crucial aspect of managing products in such an environment is controlling the number of categories a seller can assign to a single product. This feature provides flexibility while maintaining organizational structure and coherence within the marketplace.

Note for Admins

  • This setting does not affect the categories available for sellers to use; it only determines whether sellers can assign a product to one or multiple categories while managing their products.


Controlling the number of categories for a single product enhances organization and navigational ease within the OpenCart Multi Vendor environment. Admins can tailor this setting to fit the specific needs and structure of their marketplace, ensuring a seamless experience for both vendors and customers.
