Editable TreeGrid (Angular)

If you use FlexGrid's childItemsPath to show the data as a TreeGrid, the resulting grid will be read-only by default. This happens because every row in a TreeGrid is a GroupRow, and group rows are read-only by default. If you want your TreeGrid to be editable, handle the loadedRows event to set the isReadOnly property of every row to false.

This example uses Angular.
