Problem:
When and how to use Layouts plugin

Solution:
The Layouts plugin works with any theme. If your theme is not integrated with Layouts, you can use it to design the content part, just like with a classic page-builder.

However, if your theme is integrated with Layouts, you are able to create layout templates for whole post types and design every part of your site, including the header, content, sidebars, and footer.

You can find proposed solution, in this case, with the following reply:
