accordian to collapsable panel

accordian to collapsable panel

So let's say I create an accordian on a page. The customer says great,
but I want to be able to open more than one panel at once.
It seems like there should be an easy way to just switch the class on
the parent object, and the rest of the items show up as collapsable
panels... without changing any of the rest of the styling.
I've seen one plugin for a collapsable div's, but it didn't use the
same syntax as accordians, so i'd have to reformat everything.
Thoughts?
