Multi-column submenus break on Bootstrap with screen width less than 992px. It looks like it may be a conflict with Bootstrap's dropdown toggle. This is using latest versions of everything, including Bootstrap 5.
When you hover over the parent link, the sublinks can be seen, but with no background and as if they have a line height of 0. See image, attached.
Workaround for now is simply not to use multi-column submenus, but I had the site looking bitchin' with them. Any guidance greatly appreciated!
