 You can also select the priority in case they have terms of more than one taxonomy.

Term list block. Displays a list of all terms in the selected taxonomy.
You can change the display by placing a template file in your theme.
<ol>
<li>template-parts/blocks/terms-block/<code>block-name</code>–<code>block-style</code>.php</li>
<li>template-parts/blocks/terms-block/<code>block-name</code>.php</li>
</ol>
Filter for <code>get_terms</code>.
<pre>add_filter( 'terms_block_get_terms_arguments', 'my_filter', 10, 3 );
function my_filter( $args, $taxonomy, $attributes ) {
 $args = array_merge( $args, array( 'orderby' => 'order' ) );

 return $args;
}</pre>

Terms Block

This plugin does just what I wanted. It looks just like the Category List block out of the box. However, it would be better if there were some CSS classes applied to the markup to make it possible to style this block effectively.

Works perfectly
