Define a Popup
Enter the Visual Builder and add a new section. In the section settings, enable the option “This is a Popup” and set the popup ID to “sample“.
Trigger the Popup
Finally, add a new button to a different section, and set the link URL to “#sample“.
Done
Now save your page, and load it without the Visual Builder – click the button to see your Popup in action!
