Field

The #[Field] property type will render a dropdown of all the currently available form fields, letting you pick one. This goes hand in hand in hand with the FieldTransformer value transformer, which will convert the selected field uid into the actual Field object when accessed in code.

To narrow down the possible list of fields shown in the dropdown, you can use the implements parameter to specify one or more interfaces that the target field must implement, to be listed.

use Solspace\Freeform\Attributes\Property\Implementations\Field\FieldTransformer;
use Solspace\Freeform\Attributes\Property\Input\Field;
use Solspace\Freeform\Attributes\Property\ValueTransformer;
// ...

#[ValueTransformer(FieldTransformer::class)]
#[Input\Field(
    label: 'Field Selector',
    instructions: 'Select a text or email field.',
    emptyOption: 'Select a field',
    implements: [
        TextInterface::class,
        RecipientInterface::class,
    ],
)]
protected ?FieldInterface $targetField = null;
