    <service class="Yavin\Symfony\Form\Type\TreeTypeGuesser">
        <argument type="service" id="doctrine"/>
        <tag name="form.type_guesser"/>
    </service>

    or if you use yml format:

    services:
        symfony.form.type_guesser.tree:
            class: Yavin\Symfony\Form\Type\TreeTypeGuesser
            arguments: [ "@doctrine" ]
            tags:
                - { name: form.type_guesser }

    use Yavin\Symfony\Form\Type\TreeType;
    
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('category'); //extension will guess field type
    
        //or this is full example with default options:
    
        $builder->add('category', TreeType::class, [
            'class' => Category::class, // tree class
            'levelPrefix' => '-',
            'orderFields' => ['treeLeft' => 'asc'],
            'prefixAttributeName' => 'data-level-prefix',
            'treeLevelField' => 'treeLevel',
        ]);
    }

    This extension assume that in tree model You have treeLeft and treeLevel fields. It can be changed in field options.
