Using Buttons

You will need to adjust the z-index of .navbar-collapse in the collapsed state if there are multiple .navbar-collapse-absolute's near each other.

Bootstrap 4 doesn't support Dropdown Menu's with Popper.js positioning inside Navbars. They align them manually via CSS classes. See Dropdown Alignment.

Don't forget to check WAI-ARIA accessibility pratices for alerts when writting your markup.
