Filters

You can set what dropdown filters appear on the post type admin edit screen by passing an array of taxonomy names to the filters() method.

$books->filters( [ 'genre', 'category' ] );

The order the filters appear are set by the order of the items in the array.

// Display the category dropdown first.
$books->filters( [ 'category', 'genre' ] );

An empty array will remove all dropdown filters from the admin edit screen.

// Don't display filters on the admin edit screen.
$books->filters( [] );
