title: Twitter Bootstrap sideways caret
body: <p>I'm using Twitter Bootstrap and some custom css (found <a href="https://stackoverflow.com/a/10143018/351614">here</a>) to have dropdown menus open up on mouseover.</p>
  
  <p>I am using the "caret" on a  on the root menu items to show the user there is more options available, I would like to use a sideways version of this for the sub menus, in that example they use a -> image however I don't think it really fits in with the rest of the UI.</p>
  
  <p>I've also tried the play icon twitter has but it doesn't quite match either.</p>
