Hello!
First of all, I want to thank you for a nice job. It works fine, but there is a thing which I recommend to change.
When it slides down, height becomes fixed, which causes problems to the container when some contents are added to it.
Could you please help me fix this thing? The main idea is to remove the inline height property from element when animation finishes.
Thanks!!
