Hide element if mouse is not over it for a certain period of time
<p>I have a dropdown menu which gets fired when mouse moves over a specific link. I want that dropdown menu to fade out if the mouse is away from the dropdown for a specific period of time?</p>

<p>Is it possible?</p>

<p>This is my jQuery for opening the dropdown menu:</p>

<pre><code>$('.cartpopup').css({'display':'none'});
$('.cart-link').bind('mouseenter',function(){
    $('.cartpopup').stop(true, true).show().animate({top: 100}, 200).animate({top: 44}, 500);
});
</code></pre>

<p>Now how can I make the popup close automatically if it is inactive e.g. mouse not over it for certain time.</p>
