         }]
      };


var testArray = new Array();
var testObject = new Object(); 
testObject.ItemName = jsondata.GetMenu[0].OutletCode;
testObject.Items =  jsondata.GetMenu[0].MenuGroup;
testArray.push(testObject);



$( document ).ready(function() {  

var inlineDefault = new kendo.data.HierarchicalDataSource({
                    data: testArray,
                    schema: {
                        model: {
                                children: "Items"
                        }
                    }
                });

                $("#treeview-left").kendoTreeView({
                    dataSource: inlineDefault ,
            dataTextField: "ItemName",

                });
});
