ExpressionPopupContent Class
An ExpressionContent element allows you to define a popup content element with an Arcade expression. The expression
must evaluate to a dictionary representing a TextContent, FieldsContent, or a MediaContent popup element as defined
in the Popup Element web map specification.
Expressions defining popup content typically use the attributes property of an element to reference values
calculated within the expression in a table or a chart.
This content element is designed for advanced scenarios where content in charts, tables, or rich text elements is
based on logical conditions. For example, if data in one or more fields is empty, you can use this element to
dynamically create a table consisting only of fields containing valid data values. You can also use this element to
create charts or other content types consisting of aggregated data values. This can be especially useful in cluster
popups.
