Collapsible using auto-animate

AutoAnimate is a zero-config, drop-in animation utility that adds smooth transitions to your web app. You can use it with React, Solid, Vue, Svelte, or any other JavaScript application.

In this blog post, we’ll look at how to use it in ReactJs


Install using your package manager of choice to add @formkit/auto-animate to your project:


yarn add @formkit/auto-animate


npm install @formkit/auto-animate


Using auto-animate to create a collapsible or accordion is very easy. All you need to do is use the useAutoAnimate hook and pass the return value to any list container. Once this is done, any child element that is removed from the div will be auto-animated!

Here’s some example code:

import { useAutoAnimate } from '@formkit/auto-animate/react'

function MyList () {
  const [animationParent] = useAutoAnimate()
  return (
    <div ref={animationParent}>
      {/* 🪄 Magic animations for your child elements */}

Working demo

I’ve created a working demo in code sandbox to show how it works live. Here’s the code and the demo embedded below.

import "./styles.css";
import { useState, useRef, useEffect } from "react";
import autoAnimate from "@formkit/auto-animate";

export default function App() {
  const [show, setShow] = useState(false);
  const parent = useRef(null);

  useEffect(() => {
    parent.current && autoAnimate(parent.current);
  }, [parent]);

  const reveal = () => setShow(!show);
  return (
    <div className="container" ref={parent} onClick={reveal}>
      <strong className="dropdown-label">Click me to open!</strong>
      {show && (
        <p className="dropdown-content">
