Angular Data Grid - Master-Detail View

The Master-Detail View allows users to expand a row ('master') and display the related content ('details') in the expanded section. To configure this feature, set the the masterDetail object's enabled property to true and use a template to specify detail section content. In this demo, the detail section displays another DataGrid.
