Hey. Thanks for Navwalker. It is a god send. So my issue:

With the release of the new Bootstrap 4, the dropdowns don't have an li class for current_page_item like on parent items. Is there any way to add an active class to a submenu item on click? I've messed around with some jQuery. The issue: If the page is refreshed, it loses the active class.

Again, thanks for making this available to everyone.
