        Most widgets yield a single subwidget, but others like RadioSelect and
        CheckboxSelectMultiple produce one subwidget for each choice.

        This property is cached so that only one database query occurs when
        rendering ModelChoiceFields.

        Wrap the given contents in a <label>, if the field has an ID attribute.
        contents should be mark_safe'd to avoid HTML escaping. If contents
        aren't given, use the field's HTML-escaped label.

        If attrs are given, use them as HTML attributes on the <label> tag.

    A container class used for iterating over widgets. This is useful for
    widgets that have choices. For example, the following can be used in a
    template:

    {% for radio in myform.beatles %}
      <label for="{{ radio.id_for_label }}">
        {{ radio.choice_label }}
        <span class="radio">{{ radio.tag }}</span>
