Invisible Custom product fields if not filled in

-- HikaShop version -- : 2.3.2
-- Joomla version -- : 3.3.3

Hi!
I've created some Custom Fields for the Products. The problem is that products could be with or without that characteristics, even when they are in 1 category, and I don't want to display Custom Field title in listing, if it doesn't contant any value inside. How can I make it?
I'm using different Custom Field types, Check boxes,datas, etc.
