Default combination with positive inventory - automatic variant selection

No more "product unavailable" messages on the product page

By default, PrestaShop displays the default product combination set in the admin panel — even if it's sold out. The customer then sees an "unavailable" message and often leaves the page, even though other variants (sizes, colors) are in stock. This PrestaShop module solves that problem by automatically selecting the first combination with positive stock and presenting it as the default on the product page.

This way, the customer immediately sees an available variant, along with its price and photo, and the "Add to Cart" button is active. It's a simple yet remarkably effective optimization that has a real impact on sales in every PrestaShop-based online store.
