How to make vertical tabs in Bootstrap? So that they are to the left of the form and, on click, open one or another form.

Answer 1

Actually not a good idea, because content height conflicts (tabs smaller than forms) and incorrect display on mobile devices can occur.
In bootstrap 4, you need to remove display: flex from .nav .nav-tabs and make float: left float on the left plus shamanize borders, etc. Here is the bootstrap site itself.
