How to I set combo box in grid cell?

[SHIN WOOCHUL]

I used cell select combo box, but I don't know how to use it,
I want  column set like this
{ title: "회사 코드", width: "120", dataIndx: "Country",
                cls: 'beige',               
                editor: {
                    type: 'select',   
                    options: function(ui){
                       
                       var itemCd = ui.rowData.itemCd;
                       alert(itemCd);
                       var formData = new FormData(document.getElementById('selectItem'));
                       $('#kitemCd').val(itemCd);
                       $.ajax({
                         type : "POST",
                          contentType: false,
                            processData: false,
                         url : "/OrderMng/odr05/selectContractList.do",
                         cache : false,
                         data : formData,
                         success : function(json,status){
                            var $cell = ui.$cell;
                              var dataIndx = ui.dataIndx;
                              var cls = ui.cls;
                            var compList = json.resultList;
                        var innerHtml = '<select id="example" name="'+dataIndx+'" multiple="multiple" class="'+cls+'">';
                             for(var i = 0;i<compList.length;i++){                                
                                innerHtml += '<option value="'+compList.compCd+'">'+compList.compNm+'</option>';
                             }
                             innerHtml += '</select>';   
                             $cell.html(innerHtml);
                         
                         }
                       });
                    }
                }
            },

[paramvir]

you can't create combo box or select list in a grid cell but you can create it as an editor.

Example: ShipCountry, Books, Ship Via columns in this demo: https://paramquery.com/pro/demos/editing_custom
