those are dynamic columns but when i make project type as grouping everything is going bad can you help me please.

the problem its adding column with rz-col-icon before each tr but in our case its nested so just donot put before the nested columns another column with class icon

also colspan for rowgroup must has the columns of all not just the basic columns

Grouping by composite columns is explicitly disabled (i.e. you cannot group by such column using drag & drop) since this feature is not yet implemented. You can group by other columns in a DataGrid with composite columns however:

Thanks for your pull request however I don't think you've covered all cases. You can first enable grouping by such columns:

and you can try grouping by any of the composite columns in our demo:

there is also a problem with getting the right column on drag start and there are several additional scenarios that should be covered: AllowCompositeDataCells, HideGroupedColumn, ShowExpandColumn and Template.
