The plugin provides a _Shopify Products_ field, which uses the familiar [relational field](https://craftcms.com/docs/5.x/system/relations.html) UI to allow authors to select Product elements.

Relationships defined with the _Shopify Products_ field use stable element IDs under the hood. When Shopify products are archived or deleted, the corresponding elements will also be updated in Craft, and naturally filtered out of your query results—including those explicitly attached via a _Shopify Products_ field.
