Product details
The details that you provide for a product affect the way that the product is displayed to customers. The details also make it easier for you to organize your products, and to help customers find products. You don't have to provide every detail for every product.
For products that don't have any variants, the Pricing, Inventory, and Shipping sections are displayed on the product details page. If you add variants, then those sections are no longer displayed on the product details page. To change the details for product variants, refer to Editing variants for an existing product.
If you want to save specialized information or files for your products, then you can add custom fields to your product pages by using metafields. If you have an Online Store 2.0 theme, such as Dawn, then you can use the theme editor to connect metafields to your theme and customize your pages according to the product or variant that's displayed.
