How can I add a data-attr to each option within an entity field type in Symfony2

Question

I am trying to work out how I can add a data-attr to each of my options within an entity type field. I have looked through the documentation ( http://symfony.com/doc/current/reference/forms/types/entity.html ) and can't seem to find any simple way of adding this.

You cannot add attributes to options in symfony out of the box. But you could look into writing your own custom field type, see: http://symfony.com/doc/current/cookbook/form/create_custom_field_type.html
