求教：后台管理员身份限制及判断身份显示下拉框

我在添加管理员的时候，通过组件multipleLimit限制只能选择一个身份，但是当我选择value为8的身份时，control组件不生效了，这该怎么处理呢？

 Elm::select('roles', '身份',[])->options(function () {
                $data = app()->make(RoleRepository::class)->getAllOptions(0);
                $options = [];

                foreach ($data as $value => $label) {
                    $options[] = compact('value', 'label');
                }
                return $options;
            })->control([
                ['value'=>8,'rule'=>[
                    Elm::select('jb_1', '平台管理员', [])->options(function () {
                        $data = app()->make(AdminRepository::class)->getAllOptions(6);
                        $options = [];
                        foreach ($data as $value => $label) {
                            $options[] = compact('value', 'label');
                        }
                        return $options;
                    })->multiple(false),
                ]],
                ['value'=>11,'rule'=>[
                    Elm::select('jb_1', '平台管理员', [])->options(function () {
                        $data = app()->make(AdminRepository::class)->getAllOptions(6);
                        $options = [];
                        foreach ($data as $value => $label) {
                            $options[] = compact('value', 'label');
                        }
                        return $options;
                    })->multiple(false),
                    Elm::select('jb_2', '其他管理员', [])->options(function () {
                        $data = app()->make(AdminRepository::class)->getAllOptions(8);
                        $options = [];

                        foreach ($data as $value => $label) {
                            $options[] = compact('value', 'label');
                        }
                        return $options;
                    })->multiple(false),
                ]]         
            ])->multiple(true)->multipleLimit(1),
