Unlock the Ability to Categorize Pages

By default, WordPress allows you to categorize Posts, but not Pages.

After adding this code snippet to your website, you’ll be able to assign a Category to Pages and a Categories column will be added to the Pages table (/wp-admin/edit.php?post_type=page).

function add_categories_to_pages()
{
    register_taxonomy_for_object_type("category", "page");
}
add_action("init", "add_categories_to_pages");

function add_categories_to_pages()
{
    register_taxonomy_for_object_type("category", "page");
}
add_action("init", "add_categories_to_pages");
