Bootstrap 5 Beta 2

Our second beta has arrived for Bootstrap 5! We delayed its release to iron out some issues with third-party libraries and stabilize our major changes. We’ve also once again shipped some awesome updates to our documentation. Next up is our final beta, which we may even promote to a stable release depending on how development proceeds. Stay tuned for that! Dropdowns Dropdowns saw a lot of work in Beta 2 because of how much has changed in both our JavaScript and in Popper.js (which we depend on for most dropdown, popover, and tooltip positioning). We’ve modified our dropdown plugin to add a new data attribute to help separate our own positioning styles with that of Popper’s. The issues we saw—like a .dropstart menu overlapping a button or an incorrect responsive .dropdown-menu-end class—were largely the result of competing positioning.
