The TreeGrid component can be rendered with checkbox on existing column and also this can be enabled by showCheckbox property as true in columns API.

For hierarchy selection between the records, we need to enable the autoCheckHierarchy property.

While using TreeGrid in a touch device, you have an option to select the checkboxes by tapping on the checkbox.

More information on the TreeGrid instantiation can be found in this documentation section.
