Currently it’s not supported.

What do you mean it’s not supported? I am currently using grouping in a grid right now:

$grid3[“grouping”] = true;
$grid3[“groupingView”] = array();
// specify column name to group listing
$grid3[“groupingView”][“groupField”] = array(“group_name”);
$grid3[“groupingView”][“groupColumnShow”] = array(false);
// Turn true to show group collapse (default: false)
$grid3[“groupingView”][“groupCollapse”] = false;

Ok, I was unable to understand the one-liner question.

Thanks for the update.
