jQuery Grid Plugin - jqGrid

Hi All,

  I am trying to set dynamic grouping for multiple columns as below. But it is setting grouping for the first column only which is added to groupFields array first. In the below case by 'name' column.

var groupFields = [];

groupFields.push('name'); //Group by is applied for this 

groupFields.push('notes'); //Not applied for this

var groupOption = new Object();

groupOption.groupField = groupFields;

groupOption.groupColumnShow = [false]; 

groupOption.groupCollapse = flagExpandGroup;

$grid.jqGrid('setGridParam', { grouping: true });                               

$grid.jqGrid('setGridParam', { groupingView: groupOption });

$grid.trigger('reloadGrid');                                

Please help,

Thanks in advance.
