title: Bootstrap dropdown RTL alignment
body: <p>Recently in the last release of bootstrap (3.2.0), I just realized that we cannot align <code>dropdowns</code> with <code>dir="rtl"</code> or<code>dir="ltr"</code> so we have to do it manually as their <a href="http://blog.getbootstrap.com/2014/01/30/bootstrap-3-1-0-released/" rel="noreferrer">official blog says</a>: (This feature added from version 3.1.0)</p>
  
  <blockquote>
    <p>Dropdowns now have their own alignment classes for easier customization</p>
  </blockquote>
  
  <p>What is that class and how can I make a dropdown list right to left?</p>
