        app.controller('myctrl', myfun);
        function myfun($scope) {
            $scope.description = '';
            $scope.selectedItem = 'select'
            $scope.items = [
                { value: "select", description: "" }, { value: "apple", description: "is a fruit" }, { value: "carrot", description: "is a vegtable" }, { value: "cashew", description: "is a nut" }
            ];
            $scope.changeItem = function () {

                var item = $scope.selectedItem;
                for (var i = 0; i < $scope.items.length; i++) {
                    if ($scope.items[i].value == item) {
                        $scope.description = $scope.items[i].description;
                        break;
                    }
