Paragraphs is the new way of content creation!
It allows you ? Site Builders ? to make things cleaner so that you can give more editing power to your end-users.
Instead of putting all their content in one WYSIWYG body field including images and videos, end-users can now choose on-the-fly between pre-defined Paragraph Types independent from one another. Paragraph Types can be anything you want from a simple text block or image to a complex and configurable slideshow.
Paragraphs module comes with a new "paragraphs" field type that works like Entity Reference's. Simply add a new paragraphs field on any Content Type you want and choose which Paragraph Types should be available to end-users. They can then add as many Paragraph items as you allowed them to and reorder them at will.
