https://community.esri.com/t5/arcgis-experience-builder-questions/custom-widget-with-multiple-output-data-sources/m-p/1645468#M20609 <P>We are developing a custom widget for Experince Builder 1.17. The widget reads data from a web service. The data consist of five tables. I tried to make the data availabe to other widgets as five output datasources of the custom widget. When watched in the debugger, everything seems to work. But Experince Builder only shows the first output data source in the Select Data dialog, so I can't select the others. Is there a way to make the Select Data dialog show all output data sources? Or is it limited to one?</P> Tue, 26 Aug 2025 06:49:50 GMT OlafEinspanier 2025-08-26T06:49:50Z https://community.esri.com/t5/arcgis-experience-builder-questions/custom-widget-with-multiple-output-data-sources/m-p/1645468#M20609 <P>We are developing a custom widget for Experince Builder 1.17.
