CMS relation field options Relation fields connect one CMS entry to another record. Use relations when content should reference shared records instead of duplicating values.

​
Relation Types

CMS supports:
  • Many to One for one selected related entry.
  • One to Many for multiple selected related entries.
  • Many to Many for multiple bidirectional-style links.
The entry form shows a searchable picker for relation fields. In the relation field’s Field tab, choose the related table. The target can be another CMS database or a supported system table. Set Display Field when one field is enough for the relation picker. Set Display Template when editors need more context. Templates use field keys, such as: 
{{title}} - {{sku}}
Good relation labels help editors choose the correct entry quickly.

​
Delete Behavior

The relation field includes an On Delete setting:
  • Set Null clears the relation when the target is deleted.
  • Cascade removes dependent records with the target.
  • Restrict blocks deletion while a relation exists.
Choose the safest option for the content model. When unsure, use Set Null or Restrict.

Common Uses

Use relation fields for:
  • Locations assigned to a region.
  • Team members assigned to a department.
  • Products linked to a collection.
  • Blog posts linked to authors.
  • Service pages linked to service categories.
