Drag 'n Drop Column-Header(s) to group column(s) and generate grouping rows data

[fletchsod]

This is a low priority enhancement request but it is a nice to have feature that is becoming more common now. jqGrid right now doesn't have built-in components to drag column(s) somewhere to generate grouping rows data result. Alternatively, we write mind-boggling JQuery scripts as a workaround to it.
