The reason we create category is to assign it to our blog posts. Here I’ll explain you how to assign category to your new blog post.
First of all, you need to write a new blog post.
After writing a blog post, in the right hand side of the screen, you’ll see a categories tab.
There you can choose the category you want to assign to that particular blog post. Make sure you tick mark the category you want to assign. You can also choose multiple categories.
