Feature reduction popup element
Since version: 1.16
The feature reduction popup element profile allows map authors to write expressions that return a dictionary representing either a rich text, fields table, or media (i.e. a chart or an image) popup element within a popup for a cluster or bin. The returned dictionary must follow the Web Map Specification for a popupElement. When the popup opens, the expression will execute using the aggregate feature's attributes as variables. The app executing the expression will render the popup element as defined by the expression.
Unlike the Feature Reduction Popup profile, this profile allows popup authors to return multiple values within a single element.
Context
The following products implement this profile:
- ArcGIS Maps SDK for JavaScript
- ArcGIS Pro
- ArcGIS Enterprise

- ArcGIS Maps SDKs for Native Apps
Spatial reference
The spatial reference of the map in which $feature
is rendered determines the spatial reference of the expression's execution context.
