Shopify Metafields are in place to customize the appearance and functionality of your Shopify store. It lets one save the specialized information that Shopify admin doesn’t capture. So, Metafields may be put to use for internal tracking. Alternately, they may display the specialized information on your online stores, such as related products or part numbers in a variety of ways.
A merchant can add Metafields to different parts of his store, such as orders, customers, collections, or products. This may be accomplished directly from the Shopify admin, or via using an app from the Shopify app store.
In case a merchant uses the Online Store 2.0 theme, then using the theme editor lets one connect most Metafields to one’s theme. Nevertheless, when one intends to add Metafields that one’s theme doesn’t support, then, one can edit one’s theme code or hire a Shopify Expert for the same.
