If you are having trouble with dot notation in EasyAdmin filters
and cannot wait for [Use filters on nested properties #4882](https://github.com/EasyCorp/EasyAdminBundle/pull/4882), you can use this workaround.

Of course, this code is not optimal and probably does not support all comparison cases, but it can still work as a foundation for your temporary solution.

### Example usage

_Tested on EasyAdmin v4.9.4_

**Entities**

> For the sake of clarity in the example, all mapping and other methods are omitted.

```php
class Location 
{
  public string $id;
  
  public string $name;
  
  public function getNiceName(): string
  {
    return \sprint('#%d - %s', $this->id, $this->name);    
  }
}

class Offer 
{
  public string $id;
  
  #[ORM\ManyToOne(targetEntity: Location::class))]
  private Location $location
}

class Contract 
{
  public string $id;
  
  #[ORM\ManyToOne(targetEntity: Offer::class))]
  private Location $offer
}

class Invoice 
{
  public string $id;
  
  #[ORM\ManyToOne(targetEntity: Contract::class))]
  private Location $contract
}

```

**Filters**

Filter by location, where `Location::class` is assosiated with `Offer::class` `(offer.location)`, and to get `Offer::class` we need to have `Contract::class` `(contract.offer.location)`.

```php
class InvoiceCrudController extends AbstractCrudController
{
    public static function getEntityFqcn(): string
    {
        return Invoice::class;
    }
  
    public function configureFilters(Filters $filters): Filters
    {
        return $filters
            ->add(AssociatedEntityFilter::new('contract.offer.location', 'Location')
                ->setFormTypeOptions([
                    'value_type_options.class' => Location::class,
                    'value_type_options.choice_label' => 'getNiceName',
                ])
            );
    }
}
```
Or filter in `Contract::class` crud

```php
class ContractCrudController extends AbstractCrudController
{
    public static function getEntityFqcn(): string
    {
        return Contract::class;
    }
  
    public function configureFilters(Filters $filters): Filters
    {
        return $filters
            ->add(AssociatedEntityFilter::new('offer.location', 'Location')
                ->setFormTypeOptions([
                    'value_type_options.class' => Location::class,
                    'value_type_options.choice_label' => 'getNiceName',
                ])
            );
    }
}
```

Also works as EntityFilter

```php
class OfferCrudController extends AbstractCrudController
{
    public static function getEntityFqcn(): string
    {
        return Offer::class;
    }
  
    public function configureFilters(Filters $filters): Filters
    {
        return $filters
            ->add(AssociatedEntityFilter::new('location', 'Location')
                ->setFormTypeOptions([
                    'value_type_options.class' => Location::class,
                    'value_type_options.choice_label' => 'getNiceName',
                ])
            );
    }
}
```
