By default, WooCommerce hides empty product categories and sub-product categories. Occasionally, it’s useful to display all the available product categories, especially when building a new WooCommerce site. Here’s a simple snippet to unhide them!
/** Show empty product categories */ add_filter( 'woocommerce_product_subcategories_hide_empty', '__return_false' ); add_filter( 'woocommerce_product_categories_hide_empty', '__return_false' );
To also display empty sub-sub categories, you may need to add this extra code too.
/** Show empty product sub sub categories */
add_filter( 'get_terms_args', function( $args, $taxonomies ) {
if ( in_array( 'product_cat', (array) $taxonomies, true ) ) {
$args['hide_empty'] = false;
$args['pad_counts'] = true; // important for grandchildren
}
return $args;
}, 999, 2 );
