jQuery Grid Plugin - jqGrid

Is it possible to have cascading dropdowns in an edit row or form?

My select columns are make and model. I have it dynamically filling initially fine, but with all makes and all models.

I need the Model to change onChange of MakeID.

{ name: 'MakeID', index: 'MakeID', align: 'left', width: 50, editable: true, edittype: 'select', editoptions: { dataUrl: '@Url.Action("_GetMakes")' }, editrules: { required: true} },

{ name:

'ModelID', index: 'ModelID', align: 'left', width: 50, editable: true, edittype: 'select', editoptions: { dataUrl: '@Url.Action("_GetModels")' }, editrules: { required: true} },

Can this be done?
