title: jQuery dropdown menu with special animation
body: <p>I want to build a dropdown menu with jQuery like the following website did:<br>

  <p>Currently I am hanging on the dropdown animation. I have no idea how they do it and can't figure out how in their code.</p>
  
  <p>My best idea was to slideDown every li element inside the ul of a main menu item. But that doesn't looks like that on the website.</p>
  
  <p>I've uploaded the project here, on jsfiddle it doesn't works well as it in stand-alone site does.

  <p>I'm glad if you can help me building this animation for my menu.</p>
