Description

It would be great if the code in the example 320 complex grouping was integrated as a feature. I think it is a natural option to be used by the user.

$scope.gridApi.selection.on.rowSelectionChanged( $scope, function ( rowChanged ) {
    if ( typeof(rowChanged.treeLevel) !== 'undefined' && rowChanged.treeLevel > -1 ) {
      // this is a group header
      children = $scope.gridApi.treeBase.getRowChildren( rowChanged );
      children.forEach( function ( child ) {
        if ( rowChanged.isSelected ) {
          $scope.gridApi.selection.selectRow( child.entity );
        } else {
          $scope.gridApi.selection.unSelectRow( child.entity );
        }
      });
    }
  });

Thanks

Research direction
Examine the ui grid selection module and treeBase API to understand how rowSelectionChanged events are handled. The provided code snippet can be integrated into the grid's core or as an example. Consider adding a configuration option to enable group selection. The existing tutorial 320 complex grouping shows the pattern. Look at source files like src/features/selection and src/features/tree base for implementation details.
