How to open links inside the Iframe popup? (PRO option)

To open your links inside the iframe popup without redirecting your users to the other site you can do the following:
Simply create an empty iframe popup and add the following class to your link: 

Ex. <a href="" class="sg-iframe-popup-1">Popup</a>

This way, you'll have an iframe popup on your link, so when a user clicks on your link an iframe popup will open up, with the page of the link inside, so the users won't be redirected by the link.
