Reference types help easily build cross-reference between Shopify objects by allowing users to select one or multiple handles based on the type of reference field.
There are 6 reference types in ACF. All values produced by ACF are either in string (non-repeatable field) or JSON string (repeatable field).
- When attribute “Allow selection of multiple values” is checked, each value will be separated by |, for example: hello|world|2020, book|shoes|pen|eraser.
