[x] Feature: replace the wrapper div of the accordion for styling

Hi,

I have a difficult design with 4 nested panels in different configurations.. At the moment it is very hard to properly style the accordions because when the <accordion> is rendered... there is always a wrapper div.. and i need to style a lot on selectors :last-child, :first-child for my design...

Is there - or can we - make an option to replace the wrapper <div> for the accordion directly?

Thanks,
Rob
