Remove all css and custom setting in the css definition of the page.
Include only jqgrid css and jquery ui css and try.
If everything is ok include one by one the other css files in order to see which causes the problem.

Regards

It's weird when i try to roll down search operations , it's look like it would be "under" the grid..look:

I think that this is a css problem.

Which version of jQuery UI is used (the CSS file of the UI)

Regards

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..
