Do you want to get top-level categories / taxonomy? The trick is to have hide_empty=0 in your snippet. In this article, we’ll show you how to list top-level categories / taxonomy in WordPress.
Instructions:
All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:
<?php
$args = array(
'type' => 'post',
'orderby' => 'term_group',
'hide_empty' => 0,
'hierarchical' => 0,
'parent' => 0,
'taxonomy' => '..if you are using a taxonomy instead of a category'
);
get_categories( $args );
?>
