Question

I would like to slide down some li’s one at a time on clicking a button .

I mocked up a little fiddle with what I currently have http://jsfiddle.net/S5T7N/ .

 <div id="dropdown">


    <h1>when you click here</h1>

    <ul>
    <li>We</li>
    <li>Will</li>
    <li>Slide Down</li>
    <li>One At A Time</li>
    </ul>
  </div>

Have a look at this JSFiddle.

$("#dropdown h1").click( function() {
    var lis = $(this).next('ul').find('li');

    $(lis).each(function(index) {
        var li = $(this);

        setTimeout(function() {
            li.slideDown(500);
        }, 500 * index);
    });
} )

This loops through each li and sets a timeout that waits for a different time for each li. It’s currently set to 500ms, as that’s the time of the animation. These values should stay the same to get a continuous looking animation.
