you can use `Relation::class` to build a select input like this

Relation::make('name');
```

this class works with vue `ViltRelation.vue`

```php
->options(array) //you can use Options::class to add new options or array ["name"=>"", "id"=>""]
->trackByName(string)
->trackById(string)
->relation(string)
->multi(true)
->model(Model::class)
```

### Custom Query

->query('customer_id', '=', 1)
```
