Extra fileds are rendered fine through the whole script expept in /components/com_osproperty/classes/compare.html.php where the array variable $fields is empty so the extra fields are not displayed.

Hi Dragan,
Currently, OS Property doesn't have feature to show extra fields in Compared list. But in your case, even you have the SQL Query to retrieve fields from extra fields Tables, the "print_r($fields)" will only show the extra fields in array format. It won't show extra fields in columns as other fields in Compare layout.
Thanks
