Note that this example defaults to opening the second panel of the accordion. This is done by setting options.selectedIndex=1.
new Rico.Accordion( $$('div.panelheader'), $$('div.panelContent') ); -or- new Rico.Accordion( $$('div.panelheader'), $$('div.panelContent'), {panelHeight:200, hoverClass: 'mdHover', selectedClass: 'mdSelected'}} );The second example specifies the height of the accordion panels and the css classes that can be associated with the accordion behaviors. There are many other configuration parameters that can be specified to modify various visual aspects of the accordion. The panelHeight is the attribute that is most commonly overridden.
