The FloorFilter widget simplifies visualization of GIS data for a specific floor of a building in your application. It allows you to filter down the floor plan data displayed in your MapView or SceneView to a site, a facility in the site, or a level in the facility.
To visualize your data based on site, facility, or level, your map must contain the related floor plan layers, with features linked together in a floor plan hierarchy. Once you define your map as floor-aware in the map properties, the interactive, on-screen FloorFilter widget appears and can be used to explore the floor-aware data based on the configured site, facility, and levels layers. The FloorFilter widget currently supports FeatureLayers, SceneLayers and MapImageLayers (map services).
The widget can also be used alongside other filtering functionalities, such as definition queries, selection, range, and time, to further control visualization. For example, you may want to visualize all of the features on a specific level in a facility, or all the office units within a range of levels in a facility.
// Initialize FloorFilter
const floorFilter = new FloorFilter({
view: view
});

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 <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" });
-
The name of the class. The declared class name is formatted as
esri.folder.className
.
-
facility String
-
The currently selected facility.
-
headingLevel NumberSince: ArcGIS Maps SDK for JavaScript 4.20
-
Indicates the heading level to use for the headings separating floors in buildings. By default, the building name is rendered as a level 2 heading (e.g.
<h2>Building name</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.- Default Value:2
- See also
Example// building headings will render as an <h3> floorFilter.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.
-
The widget's label.
This property is useful whenever the widget is controlled by another one (e.g. Expand)
-
level String
-
The currently selected floor level.
-
longNames Boolean
-
Determines if the widget is expanded or collapsed. If the value is
true
, the widget is expanded and the long names appear. Otherwise, short names are used and icons appear alone on buttons.
-
site String
-
The currently selected site.
-
A reference to the MapView or SceneView. If this property is set, the FloorFilter widget will update the view's floors property whenever the floor filter is manipulated or updated programmatically. This property will affect any floor-aware layer in the view.
-
viewModel FloorFilterViewModelautocast
-
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 FloorFilterViewModel class to access all properties and methods on the 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 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;

Method Details
-
addHandles(handleOrHandles, groupKey)inheritedSince: ArcGIS Maps SDK for JavaScript 4.25
-
Adds one or more handles which are to be tied to the lifecycle of the object. The handles will be removed when the object is destroyed.
// Manually manage handles const handle = reactiveUtils.when( () => !view.updating, () => { wkidSelect.disabled = false; }, { once: true } ); this.addHandles(handle); // Destroy the object this.destroy();
ParametershandleOrHandles WatchHandle|WatchHandle[]Handles marked for removal once the object is destroyed.
groupKey *optionalKey identifying the group to which the handles should be added. All the handles in the group can later be removed with Accessor.removeHandles(). If no key is provided the handles are added to a default group.
-
A utility method used for building the value for a widget's
class
property. This aids in simplifying CSS class setup.Parameterrepeatable The class names.
ReturnsType Description String The computed class name. Example// .tsx syntax showing how to set CSS classes while rendering the widget render() { const dynamicIconClasses = { [CSS.myIcon]: this.showIcon, [CSS.greyIcon]: !this.showIcon }; return ( <div class={classes(CSS.root, CSS.mixin, dynamicIconClasses)} /> ); }
-
