The first thing to understand about setting up a Blog is that posts are a post type in WordPress, in the same way that pages are. So, setting up a Blog in Avada requires you to first create Blog posts, and then you can display them on your site. This can be done in various ways, but the most current method that also provides the most flexibility is to use a Layout and a Post Card to display the posts. See the Legacy documentation on previous methods, such as the Blog and Recent Posts Element.
The ‘Post’ Post Type gathers your blog items together in a collection, separate from other post types, and also provides options for Categories, and Tags, which allow for further filtering and sorting down the track.
