Maybe this will be helpful to others (I'm afraid it's a bit of a hatchet job; and totally plagarised from the pages plugin), but I managed to get it working as a widget to display the content created by a user completing and submitting a content form.

     $num_display = (int) $vars['entity']->pages_num;
     if (!$num_display) {
         $num_display = 10;
     }
    
     $pages = elgg_list_entities(array('types' => 'object', 'subtypes' => 'form_data', 'container_guid' => page_owner(), 'limit' => $num_display, 'full_view' => FALSE));
   
   
     
     echo "<div id=\"pages_widget\">" . $pages . "</div>";
     
     $user_inbox = $vars['url'] . "mod/form/my_forms.php?id=26&form_view=mine" . page_owner_entity()->username;
     echo "<div class=\"widget_more_wrapper\"><a href=\"{$user_inbox}\">".elgg_echo('form:more')."</a></div>";
    
?>

It's probably not a very good example of coding and 'how to', but I have seen a couple of threads asking for the same thing and it might work as a solution for others.

However, now that I've got this far, I wondered if a proper professional can help with the last tiny little bit?

My form has a field named 'title'. I want the content of this field to appear in the listing - please see image below:

I did manage to get the title to display when I tried modifying the 'bookmarks' widget - but I can't reproduce it : (
