Hide filter name if non value is visible

Hi,
If I set "Dinamic display" in the filter options, it is possible and correct that no fields are shown in the filter list on front end.
The problem is that, if no fields are shown, the filter name is still shown.
Is it possible to hide the filter name if no fields are shown?
Thank you.
Nico

I've found the solution.
Change product/filter.php on line 160

FROM:
if(!empty($html[$count])){

TO:
if(!empty($html[$count]) && strpos(@$html[$count], 'checkbox') !== false){
