Templates are custom post types with just the Muffin Builder inside them. You can create a layout for your website and then use it on other pages.
Display on a page
Once you have created your template, you can then import it on any page you want. To do this, edit a page/portfolio/post and go to the Muffin Builder. Below it you will see an option to import/export the current Muffin Builder content or to choose a template import ( this option shows when you click the import button)
