Step 1: Adding Blog Categories
You'll need to categorize your blog posts before you can add multiple blog sections. Check and follow the steps in this article.
Step 2: Adding Multiple Blog Sections
After you've written some blog posts and added categories, you can add a second (or more) “Simple Blog” section anywhere on your site. Note that new blog sections will automatically share all the blog posts and settings you’ve already added.
Step 3: Display Different Blog Categories in Different Blog Sections
In the blog section, you can filter which category you want to show. By default, a blog section shows blog posts from all categories. You can display one category per section by clicking the "All Categories" dropdown in line with the "Layout" and "Background" buttons.
