I’ve got soft reject for WP with this comment:
1. Add your search forms using https://developer.wordpress.org/reference/functions/get_search_form/ function instead of hard-coding the form.
I understand that I can use searchform.php to pull the form from there. But I have few different forms in a theme. They all have different classes. For example I have navigation form with .nav-search class and mobile form with .nav-mobile-search class. How to achieve it?
