I don't understand where to look for the file in opencart 2?

Question

opencart

Good afternoon. I'm trying to Russify the template for opencart 2.2. It was possible to Russify the menu for desktops, but it’s impossible to figure it out with the mobile one: replace CATEGORIES with CATEGORIES and understand for what reason the categories of goods removed from the desktop version hang in the drop-down menu.
The code is as follows:
<?php echo 'categories'; ?>
<?php echo $_menu ?>
<?php echo $hozmegamenu; ?>

Answer 1

<?php echo 'categories'; ?> replace with <?php echo 'categories'; ?>
<?php echo $_menu ?> - here is the output of one menu
<?php echo $hozmegamenu; ?> - here is the output of another
one you changed, now edit the second
