How to theme webform component? I want to change the order of a webform component. This creation of a webform component:

$component = array(
      'name' =&gt; key($question_name),
      'form_key' =&gt; $key,
      'type' =&gt; $form_type,
      'mandatory' =&gt; 0,
      'weight' =&gt; $weight,
      'pid' =&gt; 0,
      'extra' =&gt; array(
          "items" =&gt; "1|1\n2|2\n3|3\n4|4",
          "multiple " =&gt; FALSE,
          "aslist" =&gt; FALSE,
          "description" =&gt; $question['description'],
        ),
);


Gives me the following display result:


Name of component 
1 - 4 radiobuttons
Descriptiontext


But I want to move the description text over the radiobuttons:


Name of component
Descriptiontext
1 - 4 radiobuttons


How can I change the order of the output?
What I was searching for was:

function THEMENAME_webform_element($variables)
