I use the K2 and I realize that there is a way to add buttons ADD THIS very easily. But, these buttons appear only on items not on the list of items in the category. That is, only after I click on the options paper that appears to enjoy, share ... When I insert PHP code directly by all the buttons are on the same amount of clicks (tanned and shared). Could someone help me?

Did you add the codes in to the K2 Parameters - Social code section ?

Yes they are only visible item is not in the category. The social buttons only appear after you click read more.

Yes, it will only load at the items page and not the category listings. What you're trying to achieve i believe is similar to this thread Click Here . Or if you like to use a commercial plugin fro USD15.00, you can check out here . I've not tried it with category listing but it does support K2 integration.
