You can programmatically open different panels by using JavaScript functions. For example, you might have a button on your page that opens a particular accordion panel when the user clicks the button.
<input type="button" onclick="acc10.openFirstPanel()" >open first panel</input> <input type="button" onclick="acc10.openNextPanel()" >open next panel</input> <input type="button" onclick="acc10.openPreviousPanel()" >open previous panel</input> <input type="button" onclick="acc10.openLastPanel()" >open last panel</input> <script type="text/javascript"> var acc1 = new Spry.Widget.Accordion("Accordion1"); </script>
