How to customize the opencart menu?

Question

opencart

I have a main category "catalog" on the site, when I go to the directory, the category looks like this - index.php?route=product/category&path=62. And it perfectly displays all the categories that I added.
If I go further into one of these categories, the url takes on the following form - /category&path=62_90 and all categories disappear, how to fix this problem?

<?php if ($categories) { ?>
        <ul class="categories">
          <?php foreach ($categories as $category) { ?>
          <li><a href="<?php echo $category['href']; ?>"><?php echo $category['name']; ?></a></li>
          <?php } ?>
        </ul>
    <?php } ?>

If you mean displaying subcategories above products, then you need to correct the category request in the category controller. Ask for all current category for 62.
