Since version: 1.28

The Feature Display Title profile allows the map author to write an expression that returns the preferred title to display for a feature (or row) in an application's UI that uniquely represents the feature. This is displayed in lieu of a layer's display field. The script evaluates for each row in the table. It is expected that the script returns a text value, comprising the title to display.

Context

The following product implements this profile:

Spatial reference

The spatial reference of the expression's data source1 determines the execution context's spatial reference.
