John, thanks for the response. I read through the link you provided and worked it out! In my case, I was able to add the following code, and because I linked it to the key of the field, it only affected that one set of radio buttons. Perfect! Here’s my code:
add_filter(‘acf/fields/taxonomy/wp_list_categories/key=field_69ee9943be86f’, ‘my_acf_fields_taxonomy_query’, 10, 2);
function my_acf_fields_taxonomy_query( $args, $field ) {
// Order by most used.
$args[‘child_of’] = ’14’;
$args[‘orderby’] = ‘title’;
$args[‘order’] = ‘ASC’;
return $args;
}
