I need to create our own style for the accordeons so I've choose "No JQuery UI Theme" on settings page. Now when an accordeon is collapsed it will be overlapping the next accrodeon. I find out that all accordeons have the same height which is set inline althought the autoheight param is set to "false". Changing this param will have no affect!
It would be nice if you can explain how to give the accordeons an autoheight without important notice.
