How Do I Add a Category Filter in WordPress?

Adding a category filter in WordPress is easy. In the WordPress admin area, go to the “Categories” screen.

Click the “Add New Category” button.

Enter a name for your category, and then click the “Create” button.

On the “Settings” screen, you will see a “Category Filter” section. In this section, you can specify which posts in your category should appear in the “All Posts” view.

To add a post to your category, select it from the “All Posts” list, and then click the “Add to Category” button.

Your post will now appear in the category, and the category will appear in the “All Posts” list.
