Hi,
yes it is, but you need the jquery Admin and have to edit the view.php of the module. See modified module which is attached to this posting. (The frontend.js of the module is'nt needed any more, but I don't know how to get rid of the call.)
In the jQuery admin, create a preset called "accordion" which uses (surprise) UI > Accordion
Then change the options of the toogle module for the head to
[[jQueryInclude?preset=accordion]]
<div id="accordion">
and for the footer to
</div>
Then only one toggle will stay open and the toggling runs smooth.
No warranty it works, it probably won't if you use it together with modules which use mootools or bring their own jquery call...
