React Accessible <Details> / <Summary>

The little runt brother of React Accessible Accordion which is probably what you want instead of this.

But if you do want HTML5 <details> and <summary> tags in React with managed state and a few accessibility improvements then this is it.

Install

yarn add react-accessible-details

or

npm i react-accessible-details

Stale?

Often projects on NPM are considered stale if they're not under active development, but that's a problem for software that does one thing and that may not need further development (unless Issues are raised). So this project is deemed stable and complete unless Github Issues are raised, so please don't be scared off by the fact that this project isn't under active development.

Usage

import { Details, Summary } from "react-accessible-details";

export default () => (
  <Details>
    <Summary>FAQ: Why Is New Zealand Missing From Maps?</Summary>
    Shush, don't tell anyone.
  </Details>
);

• Details takes optional props of isOpen (boolean to force open/closed), isOpenDefault (boolean to set initial value), and className (string).
• Summary takes an optional prop of className (string).

Features

Accessibility fixes like role="button" on the <summary>, setting an appropriate tabindex, and using aria-expanded to help screen readers know whether it's open or not.

As it's a React component it integrates better with a React state manager, and it implements <details><summary> in browsers that don't support it, like IE11.

It works without JavaScript (ie, server-side rendered React when browsers have JavaScript disabled) providing that browsers natively support <details> and <summary>.

It's 2KB.

Requirements

No dependencies except peer dependencies on React 16.8 or later as it uses useState and the new context API.

Styling

This component doesn't include any styling, and although it will work in IE11 you may need to provide some default styles for that browser such as display:block on the <summary> tag.

Because both components support className props they're compatible with Styled Components.
