This sample demonstrates how to use FeatureLayer.applyEdits() to update attributes of existing features. This sample uses the FeatureForm widget to update attributes of existing features by calling the applyEdits function when a user selects a feature on the view.

The form's fields are configured via a form template. This template accepts an array of field elements combined in a group. Having grouped field configurations provides a more manageable editing workflow. This sample uses nested elements which autocast to group elements.

Prior to version 4.16, formatting fields and groupings was handled via FieldConfig and/or FieldGroupConfig configurations. Moving forward, the preferred way is through setting a feature layer and/or form's formTemplate property. This property accepts an array of field and/or group elements.
