RelationshipContent | API Reference | ArcGIS Maps SDK for JavaScript 4.31

A RelationshipContent popup element represents a relationship element associated with a feature. This can only be configured if the related layer or table is added to the map.

RelationshipContent provides a way to browse related records of the current selected feature within its popup, as shown in the images below. The Origin Feature image shows a popup template configured with RelationshipContent. When selecting one of the related features in the list, the popup template for the chosen related destination feature displays. The Related Destination Feature image shows the destination popup template content with FieldsContent and RelationshipContent configured. When exploring a related feature's RelationshipContent, one could navigate into that feature's related records or exit the origin feature's related record exploration with the arrow button.

Origin Feature	Related Destination Feature

Note

The related layer or table must also be added to the map to be able to configure RelationshipContent.
Only up to 10 related features can be displayed in the list of related records.
For feature services, viewing related records is only supported for ArcGIS Online and ArcGIS Enterprise version 11.2 or higher.
For map services, viewing related records is only supported for ArcGIS Online and ArcGIS Enterprise version 11.3 or higher.
