Free Shipping to specific products ?

Is it possible to atribute Free Shipping to specific products ?

I have products i can send by free shiping but others i can't, once i enable the free shipping option it shows that option on any product the client may buy and i just want that to happen on certain products. That can be done ?

Thanks guys

see the module in this reply here: http://forum.opencart.com/viewtopic.php ... 14#p456114

Or set the weight to zero on those products and then use the weight based shipping module with 0:0 for the zone you want to ship for free to.
