Example #1 - Base Map Gallery
Use the BasemapGallery widget to select a map's basemap. This widget presents a gallery of base maps that can be user-defined or generated by a query from ArcGIS.com.
Example #2 - Geocoder
This sample demonstrates how to use the Geocoder widget to simplify
the process of finding locations on a map.
Example #3 - Home Button
Quickly return to the map's default start extent using the HomeButton widget. When the widget is created the developer specifies an extent that will be used as the 'home extent'. As users pan and zoom around the map they can click the home button to return to the specified start extent.
Example #4 - Locate Button
Find and zoom to the users current location using the LocateButton widget. This widget uses the geolocation api to find the users current location. Once the location is found the map zooms to that location.
