mega accordion height issue

Hi,
I am using your mega addon accordion element.I have an issue with the panel height.There is a fixed height assigned to the panel so If panel content is less then it shows lots of white space so what I want is to set its height according to content.

To do this when I set its height to auto the height issue got solved but when tried to close the accordion panel its transition does not remain smooth means its height then fluctuate.so basically I want its height to be according to content.
One more thing accordion panel height property is inline so where should I find it because I have not set it.
