title: Bootstrap which style controls the hover style for an active parent menu item
body: <p>I am doing a dropdown menu in Bootstrap and I want to know which style enables the active background style(highlighted) to remain active while the cursor is hovering on its child item.</p>
  
  <p>The code uses bootstraps default classes.</p>
  
  <p>It's driving me nuts trying to find it!</p>
  
  <p>I found a jsfiddle done by @Andres Ilich, it shows bootstrap with a <code>multi level dropdown</code>
