It is possible to group some fields in the edit form?
I would like to group some fields together, give them a summarizing name and give the group some different backg
What you can do is almost free modifying of Add or Edit form inside of beforeShowForm callback. I demonstrate the idea on the demo which I quickly made for you. The example shows just an example of what you can do:

The corresponding code is
$.extend($.jgrid.edit, {
recreateForm: true,
beforeShowForm: function($form) {
$('<tr class="FormData"><td class="CaptionTD ui-widget-content" colspan="2">' +
'<hr/><div style="padding:3px" class="ui-widget-header ui-corner-all">' +
'<b>Invice information (all about money):</b></div></td></tr>')
.insertBefore('#tr_amount');
$('<tr class="FormData"><td class="CaptionTD ui-widget-content" colspan="2">' +
'<hr/><div style="padding:3px" class="ui-widget-header ui-corner-all">' +
'<b>Delivery information:</b></div></td></tr>')
.insertBefore('#tr_closed');
}
});
I set $.jgrid.edit only to change beforeShowForm for both "Add" in "Edit" forms. The 'amount' and 'closed' used in .insertBefore('#tr_amount')) and insertBefore('#tr_closed') are the column names from the colModel.
