Gathering extra information with cart attributes
Cart attributes are a Shopify feature that allows you to gather extra information about an order, such as a delivery day, a gift message, or similar information.
Our theme does not allow adding arbitrary cart attributes, as each store has its own requirements and specific information to gather. Consequently, to gather extra cart information, you must either install an app (you can reach Shopify support for some recommendations) or hire a developer. Our support team does not offer coding support to do that.
