Add Facebook share button

Is it possible to add facebook share button?
I also use another template "News2" and button is present.
I know that I can use an extension but it doesn't work with k2

Thanks!

Hi, so use social module
or
use this: Bang2Joom Social Sharer Plugin (K2 support!)

I installed the plugin that you mentioned.
But it shows only "facebook like button" i would add both "like" and "share".

How can I use social module for this purpose?
How can I add that module at the end of k2 articles?

thanks in advance for your attention

How can I add that module at the end of k2 articles?

If you don't use comments system it would be quite easy.
Each template have module positions yes,
so if this K2 Item category are assigned to one of menu items - you can show Social Module on it always,
or use sidebar position.

...i would add both "like" and "share".

There is another way.

use Social icon code from services like :
https://www.addtoany.com/buttons/for/website
or
https://www.addthis.com/get/sharing
and insert inside K2 settings
...and use them instead default from template, which should be disabled in this case.

or try this one (both free):
SP Share Plugin
or
BT Social Share plugin

K2 support also!
