Does Shopify show out-of-stock products?

Yes, the product will be displayed, but the image will be blurred, indicating that the product is out of stock. If you want to hide a product automatically when out of stock, follow these steps:

1. First, you need to enable inventory tracking.
2. Click on your desired collection and find the 'Conditions' section.
3. Choose 'All Conditions' for 'Product Must Match.'
4. Now select 'is greater than 'inventory stock' and enter 0.

Bingo! Whenever your collection has 0 items left, the product will hide from the catalog automatically.
