First of all great job on your api for embedding ES fields into other pages. However I'm having an issue with extra characters showing up in the custom field type: Multi Dropdown List:

1. I have created this field in Profile types ES

2. Im using your API (as given by your developer doc) to embed this into another page:

<?php $userId = JFactory::getApplication()->input->getInt('user_id');

	$key = 'ARTMEDIUM'; 

	$my = FD::user($userId); 

	$fieldData = $my->getFieldData($key); 

	echo $fieldData; 

	?>

3. However you will see in this screenshot that extra brackets and Quotes appear with this field type. This does not happen on other fields for example a text field. (Note: I'm good with the commas) but how do I remove the brackets and quotes.

Thanks!
