# Custom filter

You can also define a custom filter by extending the `BaseFilter` class. This is useful when you want to define a filter that is not provided by LaraGrid.

```php
use BoredProgrammers\LaraGrid\Filters\BaseFilter;
use BoredProgrammers\LaraGrid\Filters\Enums\FilterType;
use BoredProgrammers\LaraGrid\Filters\Enums\FiltrationType;

class MyCustomFilter extends BaseFilter
{
    public static function make(): static
    {
        $filter = new static();
        $filter->setFiltrationType(FiltrationType::DATE_BETWEEN);
        $filter->setFilterType(FilterType::DATE);
        $filter->setBuilder(function ($query, $field, $value) {
            $query->whereBetween($field, $value);
        });

        return $filter;
    }
}
```
