Understand Metafield Structure

Metafields are a powerful way to add custom data to your Shopify store. They can be used to store anything from product specifications to customer notes. Metafields are stored in a hierarchical structure, with each metafield having a namespace, a key, a value, and a data type. Please check on this help document from Shopify to understand more about the Metafield.

The value for each metafield will be entered in the Shopify admin for each product.

Determine the Namespace

A namespace is a container for related metafields. It helps organize and group metafields together. Choose a unique namespace for your metafields that reflects their purpose or the app or plugin they are associated with. For example, you could use custom_fields or product_attributes as your namespace.

Define the Metafield Key

A metafield key is a unique identifier within a namespace. It distinguishes one metafield from another. Choose a descriptive key that represents the specific data you want to store. For example, if you want to store the product’s description, you could use the key description.

How to set up Product metafield

Electro theme only supports product metafield type. Product metafields can be used in the Product Specification, Product Comparison, and Feature Product list sections.

Metafields allow you to store and manage custom data specific to your products. They provide a flexible way to extend product information beyond the standard attributes.

You can add metafields to your products, collections, customers, orders, and other parts of your store, directly from your Shopify admin.

Step 1: Access metafield from your Shopify admin > Settings > Custom data


Step 2: Choose the option to add the metafield.


Step 3: Add name and description for the metafield
Fill in the Name and Description (optional) for the metafield then click save and this metafield will appear on all Shopify products. In this case, the Metafield namespace is custom and the Metafield key is screen_size.

How to use product metafield on Electro themeClick to copy

Electro supports three sections that can use product metafields to show information for each product: Feature Product List, Product Comparison, and Details Specification.

To use product metafields on these sections, follow these steps:

Step 1: Add the metafield namespace in the theme settings.
To add the metafield namespace in the theme settings, go to Online Store > Themes > Customize > Theme Settings > Product information > Metafields. In the Metafield Namespace field, enter the Metafield namespace you want to show. In this example, it’s “custom“.


Step 2: Add the metafield keys in the text boxes on each section.
The metafield keys are the names of the metafields that you want to use on each section. For example, if you want to use the metafield product_color on the Feature Product List section, you would enter product_color in the text box for that section.

The metafield keys that you can use on each section are listed in the guide articles for the Feature Product List, Product Comparison, and Details Specification sections.
