Master-Detail View
Documentation
The DataGrid widget supports the master-detail interface. This interface supplies a standard data row with an expandable section that contains detail data rows. Master-detail data representation is configured using the masterDetail object. In this example, each data row is supplied with a detail section that contains another DataGrid widget.
