CMS Request: Enable Reference and Multi-Reference Field Types in External Collections
Collecting votes
Currently, it is not possible to enable reference or multi-reference field types in external collections connected to the CMS.
This feature would provide greater flexibility, allowing you to use reference fields to link entries in an external collection to another collection, and use multi-reference fields to associate multiple related entries, such as products linked to multiple tags.
We are always working to update and improve our products, and your feedback is greatly appreciated.
