In order to prevent your sales representative from mistakenly selling the option products without a bundle, you can now hide the Add to Cart and Configure buttons from the Catalog and Bundle pages. This enhancement is also useful when your customer searches for an option product using the Global search and tries to add it to the cart without buying its associated bundle product. This creates a clear difference between the standalone and option product on the Catalog page.
With this feature, for each option product, the text Sold as Option is displayed when you add the option product from the Catalog page without its bundle product.
To use the above enhancement, go to Custom Settings> Config Select Products Settings and select Disable Add To Cart for Option Products. For more details, refer to Configuring Custom Settings.
