The Content widget allows to include the content of a post. You can display your content format as:
- Text only, that means it will appear unformatted
- Text with automatic <p>
- Interpreted by the Shortcode the_content
You can also state how many characters you want to show, so that you can create a shorter version of your content. Moreover, if you need to, you can select the source choosing dynamically among the content of the same page or from other specific posts.
