jQueryUI show/hide animation issue with child nodes - css

Question

I'm having trouble with the show()/hide() function of jQueryUI. They basically deactivate my CSS for the duration of the animation.
jsFiddle link: http://jsfiddle.net/UBATE/1/
According to the API:
http://docs.jquery.com/UI/Effects/Drop,
I've built the following function:
updateTeamLists = function(args) {
// fade out -> rebuild the content -> fade in
$("#team1, #team2").hide("drop", {"direction": "right"}, 600, function() {
rebuildTeamLists(args);
$(this).show("drop", {"direction": "right"}, 600);
});
};
The child DOM nodes appear to lose all their CSS attributes in the beginning of the animation, i.e. they stop floating (or lose their inline-block display) and their backgrounds vanish instantly. However, the animation and the fading out of the text work fine.
HTML DOM structure:
<div id="teams">
<div id="team1">
<ul>
<li>Player 1</li>
<li>Player 2</li>
<li>Player 3</li>
<li>Player 4</li>
<li>0 Pts</li>
</ul>
</div>
<div id="team2">
<ul>
<li>Player 5</li>
<li>Player 6</li>
<li>Player 7</li>
<li>Player 8</li>
<li>0 Pts</li>
</ul>
</div>
</div>
CSS:
#content > #teams {
margin-top: 10px;
padding: 5px 5px 5px 22px;
width: 650px;
border: 2px solid #bfbfbf;
-webkit-border-radius: 10px;

#content > #teams > div:last-child {

padding-top:3px;
}
Unfortunately I can't host the code online for a demo so I've posted up anything I got. I'm using Google Chrome 17.0.963.56 and Firefox 10.0.2.
I'm quite often having trouble with adding jQueryUI effects to my scripts, ending up not adding them. Though there might be some tricks/bugs preventing it from working (e.g. if your DOM node didn't have a class attribute, toggleClass animations wouldn't work).
Did I miss something? How would a workaround look like, would I have to iterate through all the child nodes?
Thanks in advance!

Answer 1

Jquery UI will add an extra div under the effected element. Example:
<div id="team1">
<ul>
...
<ul>
</div>
When the effect is applying, the structure will be:
<div id="team1">
<div class="jquery-ui something-else">
<ul>
...
</ul>
</div>
</div>
The solution is not to use the direct-child selector ">". See example here. You can compare it with your version :)
