Symfony2: How to add/remove entry forms for the collection field type?

I have a form that contains a collection field-type.

However I don't know how to add/remove fields to/from the collection.

$builder        
    // ...              
    ->add('covers', 'collection', array(
          'required'     => false,
          'type'         => new BookCoverType(),
          'allow_add'    => true,
    )) 
;

The rendered form looks like this:

How can I add a new cover using the collection form field?

Symfony does not provide the add/remove JavaScript methods/buttonss or any session-based solution without JavaScript out of the box.

It renders a data-prototype attribute that can be used as described in the documentation chapter How to Embed a Collection of Forms -> Allowing "new" tags with the "prototype".

Some bundles provide this functionality though. Those are primarily the bootstrap bundles:

Just dive into their code - i.e. braincrafted/bootstrapbundle's bc-bootstrap-collection.js.
