How to add a map extent indicator inset?

[PeterLen]

Hello,

I am using the Esri Javascript v3.9 (yes, I know it is older) and am trying to find some info on the best way to add an extent indicator (or whatever it is called) to my web map.  I essentially want a small map displayed in an inset in the bottom left or right corner on my main map where the inset is the same map location but zoomed out a couple of levels with the main map's extent outlined in the inset.  I found sort of an example that uses the Google Maps API, but am trying find a good example using the Esri javascript API so that I will know how to best build it.

Thanks - Peter

Take a look at the OverviewMap widget it should do what you need and it has been available since version 2.0 of the ArcGIS API for JavaScript.
