Making Bootstrap Dropdowns More Accessible
Marius Craciunoiu

Although this article has been published for a while, I would like to note that the ´aria-expanded´ attribute should be applied in the ´.dropdown-toggle´ element, not in the ´.dropdown-menu´ one as seen in the BS documentation, by the other side the later could have the ´aria-hidden´ attribute applied to it.

Anyway this article was extremely useful for me. Thanks!
