Hello,

First of all the link provided here is broken.
I can not understand exactly your requirement- you want to have not grouped rows, but in the sane time these “non groped” rows should have group header.

When you apply a grouping to some criteria it is applied to all data.
You can modify your response so that the data that you want not to be grouped to have a certain value in the grouping criteria. If you know this value you can maybe use gridComplete to color your grouped and “non-grouped” rows.

Kind Regards,
