I am using a repeater to manage a pivot table like this: I don't want users to be able to attach the same affiliate twice ```php Repeater::make('campaignAffiliates') ->schema([ Forms\Components\Select::make("affiliate_id")->relationship('affiliate', 'company_name')->required()->columnSpanFull(), Forms\Components\ToggleButtons::make('cap_type')->inline() ->live()->default('unlimited') ->options(['unlimited'=> 'Unlimited', 'daily'=>'Daily', 'weekly'=>'Weekly']) ->colors(['unlimited'=>'success', 'daily'=> 'warning', 'weekly'=>'primary']), Forms\Components\TextInput::make('cap')->hidden(fn ($get) => $get("cap_type") == "unlimited")->numeric() ])->columns(2) ->relationship(), ```
