Begin by creating a new post (or page).
Select “Use The Divi Builder” button.
Once you click the Divi Builder button, this screen will appear.
Chose the green tab that says “Clone Existing Page”
Here are a few of my exisiting pages with layouts I can chose to duplicate.
This comes in handy when you have one page that has an amazing layout deign, and you want to replicate the design for new content.
Chose an exisitng page.
Now you have the layout duplicated from your exisitng page onto this new post / page.
You can now edit the information for new content, or you can use this duplicated layout to visualize changes for the exisitng page.
