WordPress categories are a very handy way to manage your posts. Make it useful to you to handle your articles as well as make it easy to locate the articles for viewers. You can have parent and child categories making hierarchical arrangement of your posts. In addition to that, one post can be into more than one category. This gives you a lot of flexibility to show exactly the posts you want, exactly the way you want them in widgets, menus or directly in your WordPress theme.
How to Create WordPress Categories
To create new categories in WordPress, you need to access the Posts -> Catgories page first. On the left side of the page you will see a tab that allows you to create categories. Fill in the category name, its slug (will be used in the category URLs) and the Add New Category button. That’s it, your first category is ready. To make a sub category, select a parent.
Also you can create and assign categories in the post editor itself.
How to Assign Posts to Categories
Once you have the category structure created, you can add posts to categories. There are two ways you can do this. The first one is to open a particular post in edit mode and place a checkbox in the category you want to assign it to.
The second way is to bulk add posts to a category. To do this go to Posts -> All Posts. Next, select the posts you want to add to a category, click on the Bulk Actions tab, select Edit and finally press the Apply button.
Once you do that, you will receive few options that you can adjust for those selected posts all at once. One of them is the Categories section. Select the category you want to add those posts to and click on the Update button. Now, the posts you’ve marked previously belong to the category you’ve chosen.
