jQuery Grid Plugin - jqGrid

I have the newest jqGrid and jquery 1.11

My problem is that the search toolbar looks weird..like size would be too small...
Morover the context menu with search operations is opened like behind of grid.. :/

 

JS:

 var paramView = {
        init: function() {
            //grid
            $("#paramList").jqGrid({
                url:'./requests.php?action=getParamList',
                datatype: "json",
                colNames:['id','Nazwa','Wartość', 'Opis'],
                colModel:[ {name:'id',index:'id', hidden: true , editable:false,     
    
editrules: {edithidden:false}},
                           
{name:'vname',index:'vname',width:20,editable:true,editoptions{size:20},searchoptions:{sopt:['eq','ne']}},     
    
                                                                  
{name:'vvalue',index:'vvalue',     
width:30,editable:true,editoptions:{size:20}},
                                               
{name:'vdescription',index:'vdescription',width:50,editable:true,editoptions:{size:20}}],     
    

                rowNum:10,
                rowList:[10,20,30],
                pager: '#pager',
                rownumWidth: 40,
                sortname: 'vname',
                viewrecords: true,
                autowidth: true,
                                shrinkToFit: true,
                sortorder:"desc",
                gridview: true,
                editurl:"./requests.php?action=modifyData",
                caption:"Parametry systemowe" });
    $("#paramList").jqGrid('filterToolbar',{searchOperators : true});
     }
}

I think that it's not CSS fault..
