Click animation always applied to last element

Go to solution Solved by Carl,

Recommended Posts

I have no doubt I'm missing something completely obvious here, but I've stared at it so long I can't seem to catch it. Basically, trying to create a simple accordion open/close animation. The animation is fine, but for whatever reason it's only applying to the last item. I'm still new to GSAP, so if while someone is looking at things, if there's a cleaner/better way to do this in general, i'd love to hear that as well. Thanks for any and all help!

Hi @Josh Mathis


Thanks for the demo. 

You were really quite close.


To get around ONLY the last item opening and closing it was just a matter of declaring the tl variable with let like so on line 13


let tl = gsap.timeline({ paused: true });


After that it seems to work fine.


if you want to just toggle the open and closed state of each faq independently on click you can simplify your click code a lot like this

See the Pen QWOLoyK?editors=0010 by snorkltv (@snorkltv) on CodePen


If you want to automatically close the open item every time you open a new item you can do something like this

See the Pen eYeOXRV?editors=0010 by snorkltv (@snorkltv) on CodePen



Notice how I'm assigning an "animation" property to each faq. This makes it easy to target a particular faq and its animation.

I recently updated my second demo. my first attempt was rushed and I had some convoluted logic on the clicks. new version is much cleaner.

@Carl Thanks so much for the help and the very quick response! I knew it was going to be something simple like that, but I'd looked at it too long for me to ever see it. And thanks for giving me both options -- close on click and close on expanding another section! I knew what I had wasn't there yet, but I couldn't troubleshoot it without getting the other part working. So thanks for saving me the time there too. I'm not totally sure why it works to set the timeline to start in the reverse state, but I do get that it works and the use-case for it. If that's in the docs somewhere and someone wouldn't mind providing a link, I'd love to read on it further. Anyways, your help got me there Carl, and it is very much appreciated!!

no problem. the key is to first understand the next line




which basically says "make the reversed state the opposite of what it currently is" which is kind of like saying "make the opened state the opposite of what it currently is".


opened means the timeline has played

closed means the timeline has reversed


since the faqs all start "closed" we need the timelines to be reversed so that when we set the reversed state to be the opposite they will play forward and open.


Hope that helps!

@CarlThat's a great explanation and I appreciate you taking the extra time to explain it for me. It would have never occurred to me to approach it like that, but it makes total sense. Thanks man!
