Transition effect for show more button

Need help creating a smooth transition for a tab I created that when pressed shows a paragraph underneath.

Here is it opened:

I know they say set the height to 0 and then have it transition to auto when clicked, I do that but when I set the height to zero then webflow doesn’t know what auto should be and it remains closed. I am just looking for any transition effect I can add that will make it look a little smoother.
