jQuery Show More / Show Less Slider

I needed a sliding show/hide panel.

The HTML was set up as follows:

<div id="rightpane">
<div id="infopanel">
<h2>Slider Magic</h2>

</div>
<div>More Details</div>
</div>

The magic jQuery required was as follows:

<script language="JavaScript" type="text/javascript">
$(document).ready(function() {
var maxHeight = $("#infopanel").css('height');
$("#infopanel").css({'height':'180px','overflow':'hidden'});
$(".showmore").toggle(showPanel,hidePanel);
function showPanel(){
$("#infopanel").animate({height:maxHeight});
$(".showmore").text('- Fewer Details');
}
function hidePanel(){
$("#infopanel").animate({height:"180px"});
$(".showmore").text('+ More Details');
}
});
</script>

Interesting features are the use of the jQuery toggle.  This calls one of two functions to open or close the panel based on its previous state.
