The ability to pull in an external website inside of your Divi Overlay popup is an extremely useful feature. For example, say you have a web design agency with a portfolio page. You could link your finished projects, but that would take the user off of your website! Instead, you could use a Divi Overlay popup with our external website template to frame the website inside of the popup. This will keep the visitor on your site 🙂
There are of course other examples of pulling in external websites inside of the popup. The sky is the limit, but just ensure the website you’re pulling in allows external framing (or it won’t work).
I highly recommend Divi Overlays to novice users and pros. It is easy to use and works with the Divi Builder and is a great alternative to traditional modals. However, the top reasons I recommend this plugin are the support and ongoing development. Support is fast and personable, which can be important when working on a deadline. The developers have updated the plugin with some great additional functionality, and they welcome suggestions from users.
