Inheritance:: Feature→Widget→Accessor

Since: ArcGIS Maps SDK for JavaScript 4.7

The Feature widget displays a graphic according to its PopupTemplate. This widget is useful in instances where you want to display information about a feature but without the use of a Popup.

If wanting to show a feature's content with PopupTemplate.actions, related records, or clustering configuration, etc., then use the Features widget.

When Arcade expressions that use $map or geometry functions are defined in any popup template content or as expression elements, the map and spatialReference properties need to be defined in the Feature widget.

Example

// Create graphic
let graphic = new Graphic({
  geometry: view.center,
  popupTemplate: {
    content: [{
      // add popupTemplate content
    }]
  }
});

// map and spatialReference must be set for Arcade
// expressions to execute and display content
let feature = new Feature({
  graphic: graphic,
  map: map,
  spatialReference: spatialReference
});

view.ui.add(feature, "top-right");

container

autocast inherited Property

Type: HTMLElement | null | undefined

Inherited from: Widget

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 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"
});

declaredClass

readonlyinherited Property

Type: string

Inherited from: Accessor

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

defaultPopupTemplateEnabled

Property

Type: boolean

Since: ArcGIS Maps SDK for JavaScript 4.11

Enables automatic creation of a popup template for layers that have popups enabled but no popupTemplate defined. Automatic popup templates are supported for layers that support the createPopupTemplate method. (Supported for FeatureLayer, GeoJSONLayer, SceneLayer, CSVLayer, OGCFeatureLayer PointCloudLayer, StreamLayer, and ImageryLayer).

Default value: false

destroyed

readonlyinherited Property

Type: boolean

Inherited from: Widget

When true, this property indicates whether the widget has been destroyed.

graphic

autocast Property

Type: Graphic | null | undefined

The Graphic used to represent the feature.

PopupTemplate.content

Example

let graphic = new Graphic({
  geometry: view.center,
  attributes: {
    "name": "Spruce",
    "family": "Pinaceae",
    "count": 126
  },
  symbol: new SimpleMarkerSymbol({
    style: "square",
    color: "blue",
    size: "8px"
  }),
  popupTemplate: {
    content: [
      {
        // Set popup template content
      }
    ]
  }
});

headingLevel

Property

Type: HeadingLevel

Since: ArcGIS Maps SDK for JavaScript 4.20

Indicates the heading level to use for the title of the feature widget. By default, the title is rendered as a level 2 heading (e.g. <h2>Title of content</h2>). 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.

Heading Elements

Default value: 2

Example

// feature title will render as an <h3>
feature.headingLevel = 3;

icon

autocast Property

Type: Icon["icon"]

Since: ArcGIS Maps SDK for JavaScript 4.27

Icon which represents the widget. It is typically used when the widget is controlled by another one (e.g. in the Expand widget).

See also

Default value: "polygon"

id

inherited Property

Type: string

Inherited from: Widget

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

autocast Property

Type: string

Since: ArcGIS Maps SDK for JavaScript 4.11

The widget's default label.

location

autocast Property

Type: Point | null | undefined

Since: ArcGIS Maps SDK for JavaScript 4.31

The location of the graphic to be displayed.

map

Property

Type: EsriMap | null | undefined

Since: ArcGIS Maps SDK for JavaScript 4.11

A map is required when the input graphic has a popupTemplate that contains Arcade expressions in ExpressionInfo or ExpressionContent that may use the $map profile variable to access data from layers within a map. Without a map, expressions that use $map will throw an error.

Alternatively, the view property can be used to provide the map instance for this property.

See also

Example

// The building footprints represent the buildings that intersect a clicked parcel
let buildingFootprints = Intersects($feature, FeatureSetByName($map, "Building Footprints"));

spatialReference

autocast Property

Type: SpatialReference | null | undefined

Since: ArcGIS Maps SDK for JavaScript 4.11

The spatial reference used for Arcade operations. This property should be set if the Feature widget executes Arcade expressions that contain geometry functions.

See also

timeZone

autocast Property

Type: TimeZone

Since: ArcGIS Maps SDK for JavaScript 4.29

Dates and times displayed in the widget will be displayed in this time zone. By default this time zone is inherited from MapView.timeZone. When a MapView is not associated with the widget then the property will fallback to the system time zone.

Possible Values

Value	Description
system	Dates and times will be displayed in the timezone of the device or browser.
unknown	Dates and time are not adjusted for any timezone.
Specified IANA timezone	Dates and times will be displayed in the specified IANA time zone. See wikipedia - List of tz database time zones.

title

readonly Property

Type: string

The title for the feature. You can disable this via the visibleElements property.

See also

headingLevel

view

Property

Type: MapViewOrSceneView | null | undefined

A reference to the MapView or SceneView. Set this to link the widget to a specific view.

The Feature widget requires a view if the user expects it to display content in any of the following situations:

The graphic has a popupTemplate containing Arcade expressions in ExpressionInfo or ExpressionContent that use geometry functions or reference the $map profile variable (i.e. access data from layers within a map).
Content is displayed from the popup template of an aggregate feature (i.e. a cluster or bin).
Values from date and timestamp-offset fields should respect the view's time zone.

viewModel

autocast Property

Type: FeatureViewModel

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 FeatureViewModel class to access all properties and methods on the widget.

visible

inherited Property

Type: boolean

Inherited from: Widget

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 DefaultUI, 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;

visibleElements

Property

Type: FeatureVisibleElements

Since: ArcGIS Maps SDK for JavaScript 4.11

The visible elements that are displayed within the widget's graphic.popupTemplate.content. This property provides the ability to turn individual elements of the widget's display on/off. See the PopupTemplate.content documentation for additional information on how these elements work.
