To hide out-of-stock products in Shopify, you can follow these steps:
By unchecking the "Continue selling when out of stock" box, the product will be hidden from your Shopify store when it goes out of stock. The product will reappear in your store when the inventory is tracked as available again.
If you have multiple out-of-stock products, you can follow these steps for each individual product, or you can use the "Bulk actions" option to select multiple products and make changes in bulk.
Remember to regularly update your inventory to ensure accurate information is being displayed on your Shopify store.
