Answer 1

I suppose the only way to do that is override rendering in the template. You should pass to your template entity MyBundle:Service and render it for example like this:

{% for service in services %}    
    <b>{{ service.name }}</b><br>
    {% for option in service.options %}                    
        <label>
            <input type="checkbox" name="form_type_name[options][{{ option.id }}]" value="{{ option.id }}" {% if option in user.services.options %}checked="checked"{% endif %}>
            {{ option.name }}
        </label>
    {% endfor %}
{% endfor %}

This can be solved by using the group_by option:

$builder->add('services','entity', array(
    'class' => 'MyBundle:Service',
    'group_by' => 'serviceType',
    'multiple' => true,
    'expanded'  => true
));
