Opening Info Window When Zooming to Layer with Zoom Grid Sidebar

ThomasMetos1 — Fri, 12 Jan 2018 21:20:09 GMT

Hi, I am new to Javascript and need some help,

I am creating a web map with the ArcGIS Javascript API based on this Sandbox template link.

When zooming to the selected feature, I would like an info window with information on the feature to popup as well.

I would like to know the best way to do this.

Thanks!
