FeatureFormWidget Class
The FeatureForm widget displays attributes of a feature. This widget renders inputs based on the feature’s attributes and whether the field allows editing. It is possible to configure elements for fields and groups of other elements. The latter is useful for organizing how your form data displays. All of the properties and configurations set on the form are handled via the formTemplate property.
This widget is intended to be used with FeatureLayer.applyEdits method. This enables an end user to update a feature’s attribute on an editable feature layer. The UI to submit and apply any updates should be wired up within the application’s code.
