jQuery Grid Plugin - jqGrid

I am still a bit of a newbie using jqgrid but find it awesome.

Is it possible to change the css styling of the dropdown select in an editable column for inline editing in the jqgrid?

I have the following css:

.farmtype {

font-size:11px;

width:75px;

}

and the following grid column:

{name:'Type',index:'Type', width:60,editable: true,edittype:'select',classes: 'farmtype', editoptions:{value:"G:General;S:Stud;T:Training",dataEvents:[{type:'change', fn: function(e) {test(e); }}]}}

Thanks
