If you want to use a block grid inside a entity you have to add the the Enhavo\Bundle\BlockBundle\Model\NodeInterface to target entity.

manyToOne:
content:
targetEntity: Enhavo\Bundle\BlockBundle\Model\NodeInterface


And add a getter and setter function to the entity class. Set the property and type of the Node correctly. In this case the type is root, because it is the entry point of the block node tree. Property should be the member name where the Node is stored. This is important to browse through the node three later.

use Enhavo\Bundle\BlockBundle\Model\NodeInterface

class MyEntity
{
/**
* @param NodeInterface|null
*/
private $content; public function getContent(): ?NodeInterface { return$this->content;
}

public function setContent(?NodeInterface $content) { if($content) {
$content->setType(NodeInterface::TYPE_ROOT);$content->setProperty('content');
}
$this->content =$content;
return $this; } }  And add a migration file and execute it to update your database schema. To show the block form, you need add the Enhavo\Bundle\BlockBundle\Form\Type\BlockNodeType to your form builder. use Enhavo\Bundle\BlockBundle\Form\Type\BlockNodeType; use Symfony\Component\Form\AbstractType; use Symfony\Component\Form\FormBuilderInterface; class MyEntityType extends AbstractType { public function buildForm(FormBuilderInterface$builder, array $options) {$builder->add('content', BlockNodeType::class);
}
}
