ESM: import FeatureForm from "@arcgis/core/widgets/FeatureForm.js";
CDN: const FeatureForm = await $arcgis.import("@arcgis/core/widgets/FeatureForm.js");
Class: @arcgis/core/widgets/FeatureForm
Since: ArcGIS Maps SDK for JavaScript 4.9
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.
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.
Example
const featureForm = new FeatureForm({
container: "formDiv",
map: map, // Required if using Arcade expressions that use the global $map variable
feature: graphic,
formTemplate: template
});
Constructors
new FeatureForm(properties)
Parameter
optionalSee the properties for a list of all the properties that may be passed into the constructor.
Example
// Typical usage
const featureForm = new FeatureForm({
container: "formDiv", // HTML div
map: map, // Required if using Arcade expressions that use the global $map variable
feature: graphic, // Pass in feature
// Specify the form's template for how it is configured
formTemplate: template
});

Property DetailsThe ID or node representing the DOM element containing the widget. This property can only be set once. The following examples are all valid use case 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
<body>
<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"
});
Inherited
Property declaredClass Stringreadonly
The name of the class. The declared class name is formatted as esri.folder.className
.
Since: ArcGIS Maps SDK for JavaScript 4.25 FeatureForm since 4.9, disabled added at 4.25.
When true
, sets the widget to a disabled state so the user cannot interact with it.
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
}
});
});
Since: ArcGIS Maps SDK for JavaScript 4.16 FeatureForm since 4.9, formTemplate added at 4.16.
The associated template used for the form.
The formTemplate is used to configure how the form should display and set any associated properties for the form, e.g. title, description, field elements, etc.
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({
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 FeatureForm since 4.9, groupDisplay added at 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 one at a time.Possible Values:"all" |"sequential"
headingLevel Number
Since: ArcGIS Maps SDK for JavaScript 4.20 FeatureForm since 4.9, headingLevel added at 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.
Example
// form title will render as an <h3>
// group element labels will render as an <h4>
featureForm.headingLevel = 3;
Since: ArcGIS Maps SDK for JavaScript 4.27 FeatureForm since 4.9, icon added at 4.27.
Icon displayed in the widget's button.
Inherited
Property id String
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.
The widget's default label.
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 4.27 FeatureForm since 4.9, map added at 4.27.
A reference to the associated Map.
This property is required if working with Arcade expressions in the FeatureForm
that make use of the $map
global variable.
Since: ArcGIS Maps SDK for JavaScript 4.28 FeatureForm since 4.9, timeZone added at 4.28.
The timezone displayed within the form. If unknown
, it first checks if the layer has a preferredTimeZone. If so, it displays this. If not, it will default to UTC.
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.
Inherited
Property visible Boolean
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"
.
Example
// Hides the widget in the view
widget.visible = false;
Since: ArcGIS Maps SDK for JavaScript 4.33 FeatureForm since 4.9, visibleElements added at 4.33.
Defines which elements are visible in the widget.
