Notice:
If you are using another plugin to add social buttons to your site, you might integrate that plugin to grid/list View using the code here (see document).
The code for // Put the text, HTML or PHP code here is the PHP function (or shortcode) to shows social buttons for a post of the social plugin (you might contact their support to know that function).

Best regards,
