Can we use Expand and Collapse functionality in dhtmlGrid?

Could you clarify what exactly do you need to expand or collapse in dhtmlxGrid?

I would like know how to incorporate the expand/collapse operation in the datagrid.

Scenario: We have the data as parent child records. But we would like to drag and drop the parent element without its child elements. It is not acheiveable in DataTreeGrid. Hence we implemented in DataGrid with different representation. We would like to know to have the expand / collapse option in the DataGrid.

Please suggest.

dhtmlxgrid have no tree-structure, so there is nothing to expand or collapse.
nodes expanding/collapsing is available in dhtmlxTreeGrid only.
