Create Replica Section
Start by creating a replica section post. It’s the exact same way when you create a simple page. Add all the elements you want.
Static Replica Section
You add static replica section to your pages using the visual composer page builder. When you add one, All the replica elements will be added as a single one. And you cannot modify them in your new page.
Alterable Replica Section
Use the add replica section button instead of the visual composer elements. So all the replica elements will be alterable and you can change settings in them as you want.
