简化后的主要代码:

        $scope.groups = [];

        for (var i = 0; i < 2; i++) {

            $scope.groups[i] = {
                name: i,

            for (var j = 0; j < 3; j++) {
                var item = { name: i + '-' + j, items: [] };

                for (var k = 0; k < 3; k++) {
                    item.items.push({ name: 'kkk' + k });
                }

                $scope.groups[i].items.push(item);
            }
        }



        $scope.toggleGroup = function (group) {
            if ($scope.isGroupShown(group)) {
                $scope.shownGroup = null;
                $scope.shown2 = null;
            } else {
                $scope.shownGroup = group;
            }
        };
