How can I add social media icons / share button to Thank you page?

I am trying to paste in code from FB for Share button on thank you page but it keeps disappearing. Can this be done? What am I doing wrong?

We do have a social share widget

http://widgets.jotform.com/widget/social_share

But this can only be added to the form itself, not the Thank you page.  Are you looking for to share the form itself in social media or another page?

I guess you might want to make a custom URL Thank You page, which would be a webpage hosted somewhere else with the social share code.

Just go to Thank You then select Custom URL

And paste the link to your webpage containing the social media share buttons
