Imo

Yup that's exactly what I was looking for thanks!

Woops sorry here's a rough Stackblitz of the problem: https://stackblitz.com/edit/nextjs-q86vud?file=app%2Fcomponents%2FControls.tsx

Hello, I'm trying to implement mounting and unmounting animations to conditionally rendered elements in my React component, similar to the example given in the Advanced React docs: {!joined && ( <div ref={usernameFormRef}> <Button onClick={() => onSubmit()}> Join </Button> </div> )} {joined && ( <div ref={controlsRef}> <Button onClick={() => onLeave()}> Leave </Button> </div> )} const [joined, setJoined] = useState(false); const { contextSafe } = useGSAP({ scope: controlsScope }); const tl = gsap.timeline(); const onSubmit = contextSafe(() => { tl.to(usernameFormRef.current, { opacity: 0, yPercent: 200, duration: 0.7, ease: "back.in(2)", onComplete: () => setJoined(true), }); tl.from(controlsRef.current, { opacity: 0, yPercent: 200, duration: 0.7, ease: "back.out(2)", }); }); const onLeave = contextSafe(() => { tl.to(controlsRef.current, { opacity: 0, yPercent: 200, duration: 0.7, ease: "back.in(2)", onComplete: () => setJoined(false), }); tl.from(usernameFormRef.current, { opacity: 0, yPercent: 200, duration: 0.7, ease: "back.out(2)", }); }); The problem I faced was that the onComplete function seemed to fire at the end of the timeline, not between each tween. This results in the tl.to unmounting/exit animation working as expected unlike tl.from which results in an abrupt mounting of the controlsRef element. I have also tried implementing without a timeline but ran into the same results. What exactly am I missing here? Any help would be much appreciated. I have also attached my component directly if more context is needed. MultiplayerControls.tsx
