Features | API Reference | ArcGIS Maps SDK for JavaScript 4.30

The Features widget allows users to view a feature's popupTemplate content such as attributes, actions, related records, etc., without having to be tied to the View. This widget looks and behaves similarly to the Popup widget, however unlike Popup, the Features widget can be placed outside of the view. For example, when features are selected in the View, the Popup widget opens within the View whether it is docked or anchored to the selected feature. With the Features widget, the same information that popup provides is shown in a separate container from the view, such as a HTML div within a Calcite Design System Shell Panel.

In the image above, a Calcite shell panel displays the Features widget along with a MapView in a separate div. A generic title and content property can be set directly on the Features widget or each individual layer's PopupTemplate can be displayed (e.g. the Olympic National Park feature's PopupTemplate that contains text, media, and relationship elements). The action bar, shown below the title in the image above, displays actions that can be defined either on the widget level within the open() method, with the FeaturesViewModel.actions property, or in the PopupTemplate of the layer. If multiple features are passed into the Features widget, the widget provides buttons to page though the features and a feature menu that allows the list of features to be displayed so the user can choose which feature content to display in the widget. The widget also respects feature reduction PopupTemplates for binning and clustering.

The Features widget should be used if needing to use the Popup functionality outside of the View. If wanting to show a single feature's content without actions, related records, clustering configuration, etc., then use the Feature widget.

Examples

// Create a new instance of Features and set this on the View's
// popup. When features are selected in the map, the Features widget
// will automatically open in its respective container.
const view = new MapView({
  container: "viewDiv",
  map: map,
  popup: new Features({
    container: "features-widget"
  })
});

// Create a new instance of Features and set the view property
// to the View along with the container that holds the widget
// such as a Calcite Shell Panel.
const featuresWidget = new Features({
  view: view,
  container: "features-widget"
});

// Use reactiveUtils to watch for when the view has a click event
// then open the Features widget in its respective container.
reactiveUtils.on(()=> view, "click",
(event)=>{
  featuresWidget.open({
    location: event.mapPoint,
    fetchFeatures: true
  })
});

Property Details

active Property active Booleanreadonly Since: ArcGIS Maps SDK for JavaScript 4.30 Features since 4.27, active added at 4.30.

Indicates if the widget is active when it is visible and is not waiting for results.

Default Value:false

collapsed Property collapsed Booleanreadonly

Indicates whether the popup displays its content. If true, only the header displays.

Default Value:false

container Inherited Property container String |HTMLElement 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

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

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

content Property content String |HTMLElement |Widget

The content of the Features widget. When set directly on the Popup, this content is static and cannot use fields to set content templates. To set a template for the content based on field or attribute names, see PopupTemplate.content.

Example

// This sets generic instructions in the widget that will always be displayed
// unless it is overridden by a PopupTemplate
featuresWidget.content = "Click a feature on the map to view its attributes";

declaredClass Inherited Property declaredClass Stringreadonly Inherited from Accessor

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

features Property features Graphic[]

An array of features associated with the Features widget. Each graphic in this array must have a valid PopupTemplate set. They may share the same PopupTemplate or have unique PopupTemplates depending on their attributes. The content and title of the widget is set based on the content and title properties of each graphic's respective PopupTemplate.

When more than one graphic exists in this array, the current content of the Features widget is set based on the value of the selected feature.

This value is null if no features are associated with the widget.

Example

// When setting the features property, the graphics pushed to this property
// must have a PopupTemplate set.
let g1 = new Graphic();
g1.popupTemplate = new PopupTemplate({
  title: "Results title",
  content: "Results: {ATTRIBUTE_NAME}"
});
// Set the graphics as an array to the Features widget instance. The content and title of
// the widget will be set depending on the PopupTemplate of the graphics.
// Each graphic may share the same PopupTemplate or have a unique PopupTemplate
let graphics = [g1, g2, g3, g4, g5];
const featuresWidget = new Features({
  container: "features-widget",
  features: graphics
  visible: true
});

goToOverride Property goToOverride GoToOverride

This function provides the ability to override either the MapView goTo() or SceneView goTo() methods.

See also

Example

// The following snippet uses the Search widget but can be applied to any
// widgets that support the goToOverride property.
search.goToOverride = function(view, goToParams) {
  goToParams.options = {
    duration: updatedDuration
  };
  return view.goTo(goToParams.target, goToParams.options);
};

headingLevel Property headingLevel Number

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

icon Inherited Property icon String Inherited from Widget

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

Default Value:null

See also

Calcite Icon Search

id Inherited Property id 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 Property label String

The widget's default label.

map Property map Map Since: ArcGIS Maps SDK for JavaScript 4.30 Features since 4.27, map added at 4.30.

A map is required when the input features have 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.

Default Value:null

See also

Example

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

promises Property promises Promise[]

An array of pending Promises that have not yet been fulfilled. If there are no pending promises, the value is null. When the pending promises are resolved they are removed from this array and the features they return are pushed into the features array.

selectedFeature Property selectedFeature Graphicreadonly

The selected feature accessed by the Features widget. The content displayed in the widget is determined based on the PopupTemplate assigned to this feature.

selectedFeatureIndex Property selectedFeatureIndex Number

Index of the feature that is selected. When features are set, the first index is automatically selected.

selectedFeatureWidget Property selectedFeatureWidget Featurereadonly

Returns a reference to the current Feature. This is useful if needing to get a reference to the Feature widget in order to make any changes to it.

spatialReference Property spatialReference SpatialReference Since: ArcGIS Maps SDK for JavaScript 4.30 Features since 4.27, spatialReference added at 4.30.

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

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

Default Value:null

See also

timeZone Property timeZone String Since: ArcGIS Maps SDK for JavaScript 4.30 Features since 4.27, timeZone added at 4.30.

Dates and times displayed in the widget will be displayed in this time zone. By default this time zone is inherited from MapView.timeZone if the view property is set. 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 Property title String

The title of the Features widget. This can be set to any string value no matter the features that are selected. If the selected feature has a PopupTemplate, then the title set in the corresponding template is used here.

See also

headingLevel

Example

// This title will display in the widget unless a selected feature's
// PopupTemplate overrides it.
featuresWidget.title = "Population by zip codes in Southern California";

view Property view MapView |SceneView

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

The Features widget requires a view if:

The features have a popupTemplate containing Arcade expressions in ExpressionInfo or ExpressionContent that may use geometry functions or reference the $map profile variable (i.e. access data from layers within a map). Alternatively, set the map property.
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. Alternatively, set the timeZone property.
Using the fetchFeatures method or the fetchFeatures option in the open method.
Using the Zoom to default action. If the view is not specified, set the FeaturesViewModel.includeDefaultActions property to false to remove this default action.

viewModel Property viewModel FeaturesViewModel

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

visible Property visible Boolean

Indicates whether the widget is visible.

visibleElements Property visibleElements VisibleElements

The visible elements that are displayed within the widget. This provides the ability to turn individual elements of the widget's display on/off.
