Hi, guys. I was searching for this solution on the forum and suddenly found it by chance in the editor.
So, the main idea was to use a Transition for “This element is visible”. But it is absent in Bubble.
Then I’ve tried to check “Collapse this element’s height when hidden” AND “Animate the collapse operation” where “Animation Style” = “Fade In/Out”. It worked for me.
I hope this post would be useful because I could not find any solution on the forum. I would be happy in case it helps at least 1 bubble developer .
