Create and Assign a Post Category (New Theme)

When creating a post, make sure to assign it to a category. This improves website organization and functionality. The user is able to sort posts by category, which allows them to more easily find content relevant to what they are looking for.  

You can use Post Categories with the Posts module. Targeting a specific category of posts is helpful if you want to display all posts from a category in one place. For example, if create a Newsletter category, you can display your newsletters as posts in one place.
