My issue is identical to that of Bootstrap 4.0.0 Right aligned navbar dropdown menu goes out of viewport when opened, however in my case I have a large number of dynamically generated buttons, each with its own dropdown menu, and they wrap around in the navbar, so .dropdown-menu-right is not an acceptable solution, because if the last element then wraps and finds itself as the first element of the second row on the left, the dropdown will exit the viewport on the left.
Consider this example (the dropdown menus are the ones labelled "scan", and each dropdown contains a form):
How can I force these dropdowns to automatically stay inside the view?
