I’m working on a WordPress site that someone else coded using Bootstrap. I added a submenu item to a submenu item, but it is appearing on top of it’s parent, rather than under it.
I found code that would add a class to the submenu, but I need to add a class to the child of the submenu item.
Parent
– A Submenu (child of main menu)
–A1 Submenu (child of A)
I created a dropdown-submenu class in the css file, but I don’t know how or where to add it to the wp_bootstrap_navwalker.php file. Code is below.

You could try this: add this to your styles.css, it’s work for me:
For the solved this problem.follow interaction…..
Add script(function($){ $(document).ready(function(){ $(‘ul.dropdown-menu [data-toggle=dropdown]’).on(‘click’, function(event) { event.preventDefault(); event.stopPropagation(); $(this).parent().siblings().removeClass(‘open’); $(this).parent().toggleClass(‘open’); }); }); })(jQuery);
