Collection Prototypes

gistfile1.html

    <form action="{{ path('form_submit') }}" method="post">
        {{ form_errors(form) }}
        {{ form_rest(form) }}
        <input type="submit" value="Save" />
    </form>
    {{ form_protypes(form) }}

would render something like:
    
    <form action="/form-submit" method="post">
        <div>
            <label for="form_name">Name</label>
            <input type="text" value="" maxlength="255" required="required" name="form[name]" id="form_name">
        </div>
        <div id="form_collection">
            <label for="form_collection">Collection</label>
        </div>
        <input type="submit" value="Save" />
    </form>
    <div style="display: none;">
        <div id="form_collection_prototype">
            <div>
                <label for="form_collection_title">Title</label>
                <input type="text" value="" maxlength="255" required="required" name="form[collection][title]" id="form_collection_title">
                <a class="remove" href="#">Remove</a>
            </div>
        </div>
    </div>
