求教：后臺管理員身份限制及判斷身份顯示下拉框

我在添加管理員的時候，通過組件multipleLimit限制只能選擇一個身份，但是當我選擇value為8的身份時，control組件不生效了，這該怎么處理呢？

?

 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', '平臺管理員', [])->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', '平臺管理員', [])->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', '其他管理員', [])->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),
