📦 React headless accordion

React-headless-accordion is a set of simple components ready to be inserted into your project. These unstyled components allow you to make a nested chord that matches the style you want.

Features

• ✅ Infinite nesting of the accordion
• ✅ Customization of the accordion style
• ✅ Accordion elements remain open when another element is open (Optional).
• ✅ Default opening of some element (Optional).

Why ❔

An accordion with the above characteristics is above all indispensable in many projects. It will be useful on a project where you have to make an accordion from scratch.

With react-headless-accordion we only focus on the style of the accordion rather than implementing all that logic.

Examples of online usage

You can find examples of use at here

Install

You can use yarn

yarn add react-headless-accordion

Or via npm

npm install react-headless-accordion

Make sure you have installed the peer dependencies as well with the below versions.

"react": "^18.2.0"

Usage

This component also exports a tiny CSS file built by tailwind. All CSS classes used in designing and customizing the select component are all custom tailwind classes which ensures that an existing tailwind project would not need to include this CSS file again.

Basic example

The accordion is built using the components Accordion, AccordionItem, AccordionHeader and AccordionBody.

Clicking on AccordionHeader will automatically open the AccordionBody with a transition.

import {Accordion, AccordionBody, AccordionHeader, AccordionItem} from "react-headless-accordion";

const App = () => {
    return (
        <Accordion>
            <AccordionItem>
                <AccordionHeader>
                    <h3 className={`accordion-title`}>Title 1</h3>
                </AccordionHeader>

                <AccordionBody>
                    <div className="accordion-body">
                        Lorem ipsum dolor sit amet.
                    </div>
                </AccordionBody>
            </AccordionItem>

            <AccordionItem>
                <AccordionHeader>
                    <h3 className={`accordion-title`}>Title 2</h3>
                </AccordionHeader>

                <AccordionBody>
                    <div className="accordion-body">
                        Lorem ipsum dolor sit amet.
                    </div>
                </AccordionBody>
            </AccordionItem>
        </Accordion>
    );
};

export default App;

Nested accordion

If you want to nest an accordion in another one, just put an AccordionItem in an AccordionBody.

<Accordion>
    <AccordionItem>
        <AccordionHeader>
            <h3 className={`accordion-title`}>Title 1</h3>
        </AccordionHeader>

        <AccordionBody>
            <div className="accordion-body">
                <AccordionItem>
                    <AccordionHeader>
                        <h3 className={`accordion-title`}>Title 1</h3>
                    </AccordionHeader>

                    <AccordionBody>
                        <div className="accordion-body">
                            Lorem ipsum dolor sit amet.
                        </div>
                    </AccordionBody>
                </AccordionItem>
            </div>
        </AccordionBody>
    </AccordionItem>
</Accordion>

Info

👉 You can nest one accordion in another infinitely.

Styling different states

Each AccordionItem exposes an open variable about its current state via render props that you can use to conditionally apply different styles or render different content.

import {Accordion, AccordionBody, AccordionHeader, AccordionItem} from "react-headless-accordion";

const App = () => {
    const data = [
        {title: "Title 1", content: "Lorem ipsum dolor sit amet."},
        {title: "Title 2", content: "Lorem ipsum dolor sit amet."},
        {title: "Title 3", content: "Lorem ipsum dolor sit amet."},
    ];
    return (
        <Accordion>
            {data.map((item, index) => (
                <AccordionItem key={index}>
                    {({open}) => (
                        <>
                            <AccordionHeader>
                                <h3 className={`accordion-title ${open ? 'accordion-active' : ''}`}>{item.title}</h3>
                            </AccordionHeader>

                            <AccordionBody>
                                <div className="accordion-body">
                                    {item.content}
                                </div>
                            </AccordionBody>
                        </>
                    )}
                </AccordionItem>
            ))}
        </Accordion>
    );
};

export default App;

Rendering a different tag for accordion components

By default, the components provided by react-headless-component except AccordionItem have a default tag. But you can change them.

Components	Default Tags
Accordion	div
AccordionHeader	button
AccordionBody	div

If you want to change the tag of one of the react-headless-accordion components you can use the Props as.

Example AccordionBody

<AccordionBody as={"ul"}>
    Lorem ipsum dolor sit amet.
</AccordionBody>

Styling accordion

All components exposed by react-headless-accordion except AccordionItem offer a Props className to style them.

Example using Tailwindcss

import {Accordion, AccordionBody, AccordionHeader, AccordionItem} from "react-headless-accordion";
import {Chevron} from "../components"

const App = () => {
    return (
        <Accordion transition={{duration: "300ms", timingFunction: "cubic-bezier(0, 0, 0.2, 1)"}}>
            <AccordionItem>
                {({open}) => (
                    <>
                        <AccordionHeader className="w-full flex justify-between items-center text-gray-600 border-b p-4">
                            <span>What is react-headless-accordion?</span>
                            <svg class={`w-6 h-6 ${!open ? '' : 'rotate-90'}`} fill="currentColor" viewBox="0 0 20 20" xmlns="http://www.w3.org/2000/svg"><path fillRule="evenodd" d="M7.293 14.707a1 1 0 010-1.414L10.586 10 7.293 6.707a1 1 0 011.414-1.414l4 4a1 1 0 010 1.414l-4 4a1 1 0 01-1.414 0z" clipRule="evenodd" /></svg>
                        </AccordionHeader>

                        <AccordionBody>
                            <div className="p-5 font-light">
                                Lorem ipsum dolor sit amet.
                            </div>
                        </AccordionBody>
                    </>
                )}
            </AccordionItem>
        </Accordion>
    );
};

export default App;

Transition

To animate the opening/closing of the accordion, use the Props transition available on the Accordion component.

<Accordion transition={{duration: "300ms", timingFunction: "cubic-bezier(0, 0, 0.2, 1)"}}>
    <AccordionItem>
        <AccordionHeader>{/* ... */}</AccordionHeader>
        <AccordionBody>{/* ... */}</AccordionBody>
    </AccordionItem>
</Accordion>
