title: multiple, concurrent jQuery effects
body: <p>I am trying to apply some fancy looking UI stuff to my web application, and I want a menu that, slides down and fades in, or, slides up and fades out at the same time</p>
  
  <p>I tried this...</p>
  
  <pre><code>if($('#Menu').css("display") == "none") {
      $('#Menu').slideDown(250).fadeIn(250);
  } else {
      $('#Menu').slideUp(250).fadeOut(250);
  }
  </code></pre>
  
  <p>...it didn't work. Only one effect occurs...Can anyone explain if it is possible to chain together effects in this way, or suggest a workaround?</p>
