Setting up your metafields

Click 'Product cards'
Scroll down to 'Table details'

Displaying custom data using metafields
Use the Metafield block to display custom data. This can be used to compare different properties or values of products in a side-by-side view. To do this follow the below steps
Navigate to your Shopify admin and select Settings > Custom data
Within the Metafield definitions click 'Products' and select 'Add definition'
For this example we can use 'Weight'. Make sure the Namespace and key are labeled accordingly. For this example I chose: 'custom.weight'. Set the type to 'Multi-line text'.
Within the Metaobject definitions click 'Add definition'. Set a name according to your metafield definition. For 'Type' select multi-line text and chose a name. For this example my metaobject key will be: 'weight.custom'.
Navigate back to a product page within your Shopify admin, scroll to the bottom of the page. You should now see your 'Product metafields'. You can set the custom data within those fields.
To display your custom data within your theme editor select the 'Product comparison' section > Add block > and select 'Metafield'.
