If you want multiple sections open at once, don't use an accordion !

An accordion doesn't allow more than one content panel to be open at the same time, and it takes a lot of effort to do that. If you are looking for a widget that allows more than one content panel to be open, don't use this. Usually it can be written with a few lines of jQuery instead, something like this:

jQuery(document).ready(function(){
	$('.accordion .head').click(function() {
		$(this).next().toggle();
		return false;
	}).next().hide();
});

Or animated:

jQuery(document).ready(function(){
	$('.accordion .head').click(function() {
		$(this).next().toggle('slow');
		return false;
	}).next().hide();
});
