Layouts plugin provides a drag-and-drop editor that is used from the WordPress administration. Using this editor, you can create layouts, assign them to specific content and design entire pages.
When you ask for help or report issues, make sure to tell us the design that you want to achieve and the layouts that you have created so far.
3. After you created a layout, you can either head to the Single Page or Post where you want to use it, and you will (in the Posts/page edit screen) see a Meta Box on the right hand, called "Template and Layout"
There you will choose your recently created Layout and assign it to the Page/Post
