jQuery Grid Plugin - jqGrid

Hello,

With: groupColumnShow

/ *
                                 grouping: true,
                                 groupingView: {
                                     groupField: ['Toto'],
                                     groupColumnShow: [false]
                                 }
* /

it is then possible to use the fields for editing, add via the dialog?

because if groupColumnShow: [false] 'Toto' in the box does not appear to change / addition.

even if:
{name: 'Toto', index: 'Toto ', width: 200, editable: true, edittype: 'select', editoptions {dataUrl 'file.php'}}

Is there a solution or is it a bug?

Thank you
