FeatureForm | API Reference | ArcGIS Maps SDK for JavaScript 4.33

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.

featureForm

Known Limitations

This widget is not yet at full parity with the functionality provided in the 3.x AttributeInspector widget. There is currently no support for editing attachments or related records solely within this widget, although it is possible to edit attachments and relationship data via the Editor widget. Please refer to the Editor documentation for any known limitations regarding this.

Examples

// Create the HTML div element programmatically at runtime and set to the widget's container
const basemapGallery = new BasemapGallery({
  view: view,
  container: document.createElement("div")
});

Example

// Create the Form template and pass in elements
const formTemplate = new FormTemplate({
  title: "Inspector report",
  description: "Enter all relevant information below",
  elements: [groupElement] // Add the grouped elements to the template
});

// Add a new feature form with grouped fields
const form = new FeatureForm({
