# Custom Builder

You can also define a custom builder for a filter. This is useful when you want to modify the query builder based on the filter's value.

```php
Column::make('name', 'Name')
    ->setFilter(
        TextFilter::make()
            ->setBuilder(function ($builder, $value) {
                $builder->where('name', 'LIKE', "%{$value}%");
            })
        ),
```
