autoDestroyDisabled
autoDestroyDisabled: booleanIf true, the component will not be destroyed automatically when it is disconnected from the document. This is useful when you want to move the component to a different place on the page, or temporarily hide it. If this is set, make sure to call the destroy method when you are done to prevent memory leaks.
- Attribute
- auto-destroy-disabled
- Default value
- false
icon
icon: stringIcon which represents the component. Typically used when the component is controlled by another component (e.g. by the Expand component).

- Attribute
- icon
- Default value
- "layer-basemap"
messageOverrides
messageOverrides: Record<string, unknown>Replace localized message strings with your own strings.
Note: Individual message keys may change between releases.
nextBasemap
nextBasemap: BasemapProperties | stringThe next basemap for toggling.
- Attribute
- next-basemap
position
position: "bottom-leading" | "bottom-left" | "bottom-right" | "bottom-trailing" | "manual" | "top-leading" | "top-left" | "top-right" | "top-trailing"slot instead.- Attribute
- position
referenceElement
referenceElement: HTMLArcgisLinkChartElement | HTMLArcgisMapElement | HTMLArcgisSceneElement | stringBy assigning the id attribute of the Map or Scene component to this property, you can position a child component anywhere in the DOM while still maintaining a connection to the Map or Scene.
- Attribute
- reference-element
showTitle
showTitle: booleanIndicates if the Basemap title is displayed.
- Attribute
- show-title
- Default value
- false
state
state: "disabled" | "incompatible-next-basemap" | "loading" | "ready"The current state of the component.
- Attribute
- state
- Default value
- "disabled"
view
The view associated with the component.
Note: The recommended approach is to fully migrate applications to use map and scene components and avoid using MapView and SceneView directly. However, if you are migrating a large application from widgets to components, you might prefer a more gradual transition. To support this use case, the SDK includes this
viewproperty which connects a component to a MapView or SceneView. Ultimately, once migration is complete, the Basemap Toggle component will be associated with a map or scene component rather than using theviewproperty.
Methods
| Method | Signature |
|---|---|
componentOnReady | componentOnReady(): Promise<void> |
destroy | destroy(): Promise<void> |
toggle | toggle(): Promise<any> |
componentOnReady
componentOnReady(): Promise<void>Create a promise that resolves once component is fully loaded.
Example
const arcgisBasemapToggle = document.querySelector("arcgis-basemap-toggle");
document.body.append(arcgisBasemapToggle);
await arcgisBasemapToggle.componentOnReady();
console.log("arcgis-basemap-toggle is ready to go!");- Returns
- Promise<void>
