jQuery Prepending a DIV by sliding it down

$('#container').prepend("<ul><li>Stuff</li></ul>').hide().开发者_如何学CslideDown();

I want the NEW UL to slide Down. but the above is sliding down the entire #container..

How can I prepend an item to the top, and then slide it down.. Kinda like how Twitter used to show you your new tweet.

Thank you.

You can try using this syntax instead:

$('<ul><li>Stuff</li></ul>').prependTo('#container').hide().slideDown();

Of course, if you're using a list like that it might be useful to construct it element by element like this:

var ul = $('<ul />').prependTo('#container');
$('<li />').appendTo(ul).text('Incoming!').hide().slideDown();
