React accordion component with customizable flexbox header



"You've got 5 seconds... and 3 are up." - Steven Seagal

Check out the demo NOW

Install via NPM:

npm install react-accordion-with-header

Import the modules:

import {
} from 'react-accordion-with-header';

Items can be passed in to <AccordionHeader /> and <AccordionPanel />:

  • as children (preferred)
  • as a component passed into the template prop (deprecated)

The elements passed in to <AccordionHeader /> can be horizontally justified and vertically aligned via their respective props 🎉 💥 🍻

  • horizontalAlignment
  • verticalAlignment

Pass in a component as a child to AccordionHeader and AccordionPanel:

(or plain html of course)

// note: due to the warning "Stateless function components cannot be given refs. Attempts to access this ref will fail."
// the components passed into <AccordionPanel> must be class components
// this allows to measure the height of the element via refs
class BodyTpl extends React.Component {
  render() {
    return <div>Look at this {this.props.item}</div>;

class MyAccordion extends React.Component {
  render() {
    return (
        {[1, 2, 3, 4].map((item, i) => {
          return (
            <AccordionNode key={i}>
                <div>This is the header</div>
                <div>It has flexbox layout</div>
                <BodyTpl item={item} />


  actionCallback = (panels, state) => {
    // fires any time headers are clicked and panels change state
    // receives array of panels: [{ panel: 3, open: true }, { panel: 6, open: true }]
    // and the AccordionWithHeader state
    console.log('panels, state', panels, state);

  render() {
    return (
      <AccordionWithHeader actionCallback={this.actionCallback}>
        // ... stuff
