You can also

:ref:`register your form type as a service<form-cookbook-form-field-service>`.

But this is *not* recommended unless you plan to reuse the new form type in many

places or embed it in other forms directly or via the

:doc:`CollectionType</reference/forms/types/collection>`.

For most forms that are used only to edit or create something, registering

the form as a service is over-kill, and makes it more difficult to figure

out exactly which form class is being used in a controller.

This is only needed if your form type requires some dependencies to be injected

by the container, otherwise it is unnecessary overhead and therefore *not*

recommended to do this for all form type classes.
