Solspace Freeform: Looping through Radio group options in template
To manually generate multi-option fields like radios, your code would look something like this:

{% set yourFieldHandle = form.get("yourFieldHandle") %}

&lt;label&gt;{{ yourFieldHandle.label }}&lt;/label&gt;
{% for option in yourFieldHandle.options %}
   &lt;div class="radio"&gt;
      &lt;label&gt;
         &lt;input type="radio" name="yourFieldHandle" value="{{ option.value }}" {{ option.checked ? "checked" }} /&gt;
         {{ option.label|raw }}
      &lt;/label&gt;
   &lt;/div&gt;
{% endfor %}
