How to add markup inside a form radio button div Currently I have a form displaying radio buttons and I added some markup to it by attaching #suffix to the form element. However, I found that this didn't do exactly what I needed. This created the following code structure:

&lt;div class='field-wrapper'&gt;
  &lt;div class='radio-button-group-wrapper&gt;
     ...
      &lt;div class='radio-button-group-inner-wrapper'&gt;
          &lt;div class='radio-button'&gt;
            &lt;input type='radio'&gt;&lt;/input&gt;
            &lt;label&gt;&lt;/label&gt;
          &lt;/div&gt;
          &lt;div class='radio-button'&gt;
            &lt;input type='radio'&gt;&lt;/input&gt;
            &lt;label&gt;&lt;/label&gt;
          &lt;/div&gt;
      &lt;/div&gt;
 &lt;/div&gt;
 &lt;div&gt;Markup goes here&lt;/div&gt;  
&lt;/div&gt;


I'm trying to figure out how to add markup inside the 'radio-button' div, right after the label tag. How can I do this? If there is no Drupal way of doing it, I can add it with javascript, but that's not ideal.

EDIT:
I have chosen to try using a custom template for this form element, but its not working. Here is my code:

'my_module_is_member_radios' =&gt; array(
  'variables' =&gt; array(
    'description' =&gt; array(),
  ),
   'template' =&gt; 'templates/my_module_is_member_radios',
),
I was able to follow @Alfred's advice above and used the #theme element to make this work.
I added this to my module theme hook:

'my_module_is_member_radios' =&gt; array(
  'render element' =&gt; 'form',
  'template' =&gt; 'templates/my_module_is_member_radios',
),


and in the template used this:

$armedForcedInfo = "some markup";
$civilianInfo = "some more markup"

$variables['form'][0]['#suffix'] = $armedForcedInfo;
$variables['form'][1]['#suffix'] = $civilianInfo;
print drupal_render($variables['form'][0]);
print drupal_render($variables['form'][1]);
