+    For more granular control over the generated markup, you can loop over the
+    radio buttons in the template. Assuming a form ``myform`` with a field
+    ``beatles`` that uses a ``RadioSelect`` as its widget:
+
+    .. code-block:: html+django
+
+        {% for radio in myform.beatles %}

+            {{ radio }}

+        {% endfor %}
+
+    This would generate the following HTML:
+
+    .. code-block:: html
+
+        <div class="myradio">
+            <label><input type="radio" name="beatles" value="john" /> John</label>

+            <label><input type="radio" name="beatles" value="ringo" /> Ringo</label>
+        </div>
+
+    If you decide not to loop over the radio buttons, they'll be output in a
+    ``<ul>`` with ``<li>`` tags, as above.
