How to soley wrap the -field in a custom -wrapper in Webform 4.x?
Use hook_form_alter and add "'#title_display'    => 'none'," and use label in prefix. e.g.

if($form_id == "content_type_node_form"){
   $form['field_name']['#prefix'] = '&lt;label for="edit-submitted-title"&gt;name&lt;/label&gt;&lt;div class="newclass"&gt;';
   $form['field_name']['#suffix'] = '&lt;/div&gt;';
}


I have not tested it but this can work.
