Feature Display Title

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

This profile does not include geometry functions and therefore does not need to define a spatial reference for the execution context.

Time zone

The time zone of the map in which the expression executes determines the execution context's default time zone.

Profile variables

Variable NameTypeDescription
$featureFeatureThe feature, or row, for which to display a title in the UI.
