This sample is similar to the Feature widget sample with the exception that this sample demonstrates docking the widget into a side panel. This is useful in circumstances where you may not necessarily want or need the associated feature's information to display directly within the map. It displays information based on the PopupTemplate using the Feature widget. The content of the PopupTemplate is saved within the referenced layer and makes use of custom text elements with chart media.
