Categories are Listing in random positions, It's needed to be Display According to their Ids, I am posting the code below for review
Site is in Wordpress and file is lib/all_categories.php
It should Be Listing like this:
Category Line A
-----Category 1
-----Category 2
-----Category 3
get_terms could help you in this, you can order it by whatever you wants
$categories = get_terms( 'category', array(
'orderby' => 'term_id',
'order' => 'ASC',
'hide_empty' => 0
) );
