Allow to use disabled class in dropdowns

[Serhii-DV]

I would like to use it something like that:

<ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu">
  <li><a tabindex="-1" href="#">Action</a></li>
  <li><a tabindex="-1" href="#" class="disabled">Disabled action</a></li>
  <li><a tabindex="-1" href="#">Something else here</a></li>
  <li class="divider"></li>
  <li><a tabindex="-1" href="#">Separated link</a></li>
</ul>

You can add that class to the LI instead of the A and you would get that behaviour

Thanks, you are right.

And I think this feature should be somehow described in components examples.

Added mention of this in #6346. Thanks!
