Ok. I tried the code from another question:
<?php
$subcategories = get_categories('&child_of=4&hide_empty'); // List subcategories of category '4' (even the ones with no posts in them)
echo '<ul>';
foreach ($subcategories as $subcategory) {
echo sprintf('<li><a href="%s">%s</a></li>', get_category_link($subcategory->term_id), apply_filters('get_term', $subcategory->name));
}
echo '</ul>';
?>
But didn't worked. Since I'll display the main categories in a H3, I did in a non-dynamic way. So yeah, It will look a LOT of PHP. And also: it's not working.

There is any way to display the main category in a H3 and the sub-categories in a one-way PHP? Because I know the problems of performance and security when I place A LOT of PHP.
Example:
H3> AUTOMACAO
UL
LI> SUB-CATEGORY
LI> SUB-CATEGORY
