Symfony 2 Array一个输入表单

Is there any way to use something like this:

 ->add('dropdown',
            'entity',
            array(
                'class' => 'ZabuluAvatarBundle:AddCategory',
                'data_class' => 'Zabulu\AvatarBundle\Entity\AddCategory',
                'required' => True,
                'query_builder' => function(EntityRepository $em) {
                    return $em->createQueryBuilder('c');
                },
                'property' => 'input',
                ))
            ;

but in an input text form?

My goal for this is to have an input type form that displays what is in the database, i.e. I have an entry from the database called "Cars", what would be displayed in the page would be an editable textbox with the word "Cars" in it. So for every entry in the database, there would be a textbox for it.
