FeatureForm

AMD: require(["esri/widgets/FeatureForm"], (FeatureForm) => { /* code goes here */ });
ESM: import FeatureForm from "@arcgis/core/widgets/FeatureForm";
Class: esri/widgets/FeatureForm
Inheritance: FeatureForm Widget Accessor
Since: ArcGIS Maps SDK for JavaScript 4.9

The FeatureForm widget displays attributes of a feature. This widget renders input fields based on the feature's attributes and whether the field allows editing. You can configure field groupings to aid in display and organization of form data. All of the properties and field configurations set on the form are handled via its template.

Use this widget, in combination with FeatureLayer.applyEdits, to enable an end user to update a feature's attribute on a specified editable feature layer(s).

Set any field configurations via FieldElement(s) or GroupElement(s) within the form's template elements.

Known Limitations

The FeatureForm widget is not yet at full parity with the functionality provided in the 3.x AttributeInspector widget. For example, there is currently no support for editing attachments or related feature attributes. Although, editing attachments is possible using the Editor widget.

For information about gaining full control of widget styles, see the Styling topic.

Property Details

The ID or node representing the DOM element containing the widget. This property can only be set once. The following examples are all valid use cases when working with widgets.

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")
});

// Add the widget to the top-right corner of the view
view.ui.add(basemapGallery, {
  position: "top-right"
});
// Specify an already-defined HTML div element in the widget's container

const basemapGallery = new BasemapGallery({
  view: view,
  container: basemapGalleryDiv
});

// Add the widget to the top-right corner of the view
view.ui.add(basemapGallery, {
  position: "top-right"
});

// HTML markup

  <div id="viewDiv"></div>
  <div id="basemapGalleryDiv"></div>
</body>
// Specify the widget while adding to the view's UI
const basemapGallery = new BasemapGallery({
  view: view
});

// Add the widget to the top-right corner of the view
view.ui.add(basemapGallery, {
  position: "top-right"
});
declaredClass Stringreadonly inherited

The name of the class. The declared class name is formatted as esri.folder.className.

disabled Boolean
Since: ArcGIS Maps SDK for JavaScript 4.25

When true, sets the widget to a disabled state so the user cannot interact with it.

Default Value:false
feature Graphic

The associated feature containing the editable attributes. A common way to access this is via the MapView or SceneView's hitTest() method.

Example
// Check if a user clicked on an incident feature.
view.on("click", function(event) {
  view.hitTest(event).then(function(response) {
    // Display the attributes of selected incident feature in the form
    if (response.results[0].graphic && response.results[0].graphic.layer.id == "incidentsLayer") {
       formVM.feature = result.results[0].graphic
    }
  });
});
formTemplate FormTemplateautocast
Since: ArcGIS Maps SDK for JavaScript 4.16

The associated template used for the form.

The formTemplate is where you configure how the form should display and set any associated properties for the form, e.g. title, description, field elements, etc.

See also
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 all elements to the template
});

// Add a new feature form with grouped fields
const form = new FeatureForm({
  container: "form",
  groupDisplay: "sequential", // only display one group at a time
  formTemplate: formTemplate // set it to template created above
});
groupDisplay String
Since: ArcGIS Maps SDK for JavaScript 4.10

Defines how groups will be displayed to the user.

Possible Values

Value Description
all All groups will be expanded.
sequential A single group will be expanded at a time.

Possible Values:"all"|"sequential"

Default Value:all
See also
headingLevel Number
Since: ArcGIS Maps SDK for JavaScript 4.20

Indicates the heading level to use for the title of the form. By default, the title is rendered as a level 2 heading (e.g. <h2>Form title</h2>). In addition, group element labels default to a level 3 heading (e.g. <h3>Group element label</h3>). Depending on the widget's placement in your app, you may need to adjust this heading for proper semantics. This is important for meeting accessibility standards.

Default Value:2
See also
Example
// form title will render as an <h3>
// group element labels will render as an <h4>
featureForm.headingLevel = 3;

The unique ID assigned to the widget when the widget is created. If not set by the developer, it will default to the container ID, or if that is not present then it will be automatically generated.

label String

The widget's default label.

layer FeatureLayer

Layer containing the editable feature attributes. If this layer is not specified, it is the same as the graphic's layer.

Example
const form = new FeatureForm({
  container: "formDiv", // HTML div
  layer: featureLayer // Feature layer
});
Since: ArcGIS Maps SDK for JavaScript 4.25

A reference to the MapView or SceneView.

This property is required if working with Arcade expressions in the FeatureForm that make use of the $map global variable.

The view model for this widget. This is a class that contains all the logic (properties and methods) that controls this widget's behavior. See the FeatureFormViewModel class to access all properties and methods on the widget.

visible Boolean inherited

Indicates whether the widget is visible.

If false, the widget will no longer be rendered in the web document. This may affect the layout of other elements or widgets in the document. For example, if this widget is the first of three widgets associated to the upper right hand corner of the view UI, then the other widgets will reposition when this widget is made invisible. For more information, refer to the CSS display value of "none".

Default Value:true
Example
// Hides the widget in the view
widget.visible = false;
