!help accordion on form does not work

Hi, I am trying to build a form to get valuable feedback. On the one hand you have people who believe in the platform I am building and I would like to give them the option to press a button and a form comes rolling down similarly to an FAQ. And have another form come down when they press the other button. I have made an FAQ work before and am trying to take the same angle here. The problem is when I want to animate the size of the form it does not work.

Any body know any more info to help?

Kind regards
