I tried with 'parent'=>0 but working with required result!

CodePudding user response：

You could use an if statement to check whether your parent category is the one you need to exclude.

So your code would be something like this:

$categories = get_categories(
  array(
    'hide_empty' => TRUE
  )
);
foreach ($categories as $category) { ?>
  <?php
  $args = array(
    'cat'       => $category->term_id,
    'post_type' => 'ourservices',
    'orderby'   => 'name',
    'order'     => 'ASC',

  );

  $the_query = new WP_Query($args);

  if ($the_query->have_posts()) {
    if ('Our Services' !== $category->name) {
  ?>

      <h2 class><?php echo $category->name; ?></h2>
      <ul class="list-group list-group-flush">
        <?php while ($the_query->have_posts()) {
          $the_query->the_post(); ?>
          <li class="list-group-item"><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></li>
        <?php } ?>
      </ul><br>
  <?php
    }
  }
  ?>
<?php }
wp_reset_postdata();
