From The Symfony Docs

• Form theming
• How to customize form rendering
• Default form div layout

What you basically need to do is to overload checkbox_widget block.

{% form_theme form _self %}

{% block checkbox_widget %}
{% spaceless %}
    
{% endspaceless %}
{% endblock checkbox_widget %}

Of course you can place your widgets in its own line with CSS (but it's not a Symfony2 question).
