Fields with multiple widgets
============================

Some fields may render as a `MultiWidget`, composed of multiple subwidgets
(for example, a `ChoiceField` using `RadioSelect`). You can use the same tags
and filters, but your template code will need to include a for loop for fields
like this:

.. code-block:: html+django

{% load widget_tweaks %}

{% for widget in form.choice %}
{{ widget|add_class:"css_class_1 css_class_2" }}
{% endfor %}
