	register_taxonomy( 'genre', array( 'book' ), array(
		'labels'            => array(
			'name'          => 'Genres',
			'singular_name' => 'Genre',
		),
		'hierarchical'      => true,
		'public'            => true,
		'show_in_rest'      => true,
		'show_admin_column' => true,
		'rewrite'           => array( 'slug' => 'genre' ),
	) );
} );

What it's for

Taxonomies group content the way categories and tags do. Registering one by hand needs the usual labels and arguments: here you fill them once and get the correct function.

Frequently asked questions

›Hierarchical or not?

Hierarchical = like categories (with parents/children). Non-hierarchical = like tags (a flat list). Choose based on how you want to organise content.
