title: Drop down only one menu at a time
body: <p>So far I have this <a href="http://fiddle.jshell.net/mareksmakosz/8aKgY/7/" rel="nofollow"><strong>drop-down menu</strong></a>. When I click on either "Menu", "Menu1" or "Menu2", the links under it will drop down. </p>
  
  <p>The problem: 
  I need to display only one drop-down at a time, so that the user can switch between them.</p>
  
  <p>I tried to apply <code>css('overflow', 'hidden');</code> to the menu currently dropped down, but it won't work, since the <code>overflow: visible !important;</code> is applied to the <code>.clicked</code> class.
  Please help, anything will be highly appreciated!</p>
