This sample demonstrates the way of binding self-referential flat data to Tree Grid component.
Tree Grid can be bound either to local or remote data services. The dataSource property can be assigned either
with the array of JavaScript objects or instance of DataManager.
In this demo, the array of self-referential flat data with parent ID is assigned as the data source to the Tree Grid.
More information on the self-referential data binding can be found in this documentation section.
