Using "publish_form_field_unique" and Formatting menu not showing

I’m using the “publish_form_field_unique” hook to make a new custom field of the type “markitup”. This extension allows one to disable (and re-enable) it with a click right on the publish/edit page, rendering just the plain text field - but the formatting menu isn’t there, even when users select to show the formatting menu.

It looks like when I use publish_form_field_unique it is a completely blank slate - I can put anything I want there, without EE adding any of the normal stuff. What If I want some of the normal stuff added in there - such as the formatting menu? Is there a simple way to return the default formatting menu (like what would be returned if the field was a regular textarea)?

I’m really looking to add just a “normal” textarea field, but of a special “markitup” type (essentially replicating the “textarea” field type but with a different name) so that Markitup will only replace textareas in fields of the type “markitup” and leave all others alone.

To give you an idea of what I have now, this is my function:

Note: My code is getting mangled no matter how I post it in here, but you’ll get the idea.

function publish_form_field_unique( $row, $field_data )
{
  
 // Check if we're not the only one using this hook
 $r = ($EXT->last_call !== FALSE) ? $EXT->last_call : "";

 if($row["field_type"] == $this->type)
 {

  $r .= '<a href="#field_id_%27.$row" class="toggle"><span>Disable '.$row["field_fmt"].' markItUp!</span></a><br clear="all" >';
  $r .= '<textarea dir="ltr" name="field_id_'.$row['field_id'].'" id="field_id_'.$row['field_id'].'" rows="'.$row['field_ta_rows'].'" cols="90" class="markitupfield '.$row["field_fmt"].'">'.$field_data.'</textarea>';
  }
  return $r;   
}

And it is returning this:

Obviously, if you look at the markup for a regular textarea field, there is a lot more in there than what you see here (formatting menu, table wrapped around the textarea, etc). I’m just looking for an easy way to replicate a textarea field type, with all the extra padded wrappers, etc and the formatting field, but with a field type of “markitup”. Any ideas are totally welcome.
