rc-collapse

What is rc-collapse?

The rc-collapse npm package is a React component for creating collapsible panels. It allows developers to create sections of content that can be expanded or collapsed by the user, making it useful for FAQs, menus, and more. It supports accordion mode, where only one panel can be open at a time.

What are rc-collapse's main functionalities?

Basic Collapse

This code sample demonstrates how to create a basic collapsible component with two panels. Each panel has its own header and content.

import Collapse from 'rc-collapse';
import 'rc-collapse/assets/index.css';

const Panel = Collapse.Panel;

const App = () => (
  <Collapse>
    <Panel header="This is panel header 1" key="1">
      <p>Content of panel 1</p>
    </Panel>
    <Panel header="This is panel header 2" key="2">
      <p>Content of panel 2</p>
    </Panel>
  </Collapse>
);

Accordion Mode

This example shows how to enable accordion mode, where opening one panel will close the others, ensuring only one panel is open at a time.

import Collapse from 'rc-collapse';
import 'rc-collapse/assets/index.css';

const Panel = Collapse.Panel;

const App = () => (
  <Collapse accordion>
    <Panel header="This is panel header 1" key="1">
      <p>Content of panel 1</p>
    </Panel>
    <Panel header="This is panel header 2" key="2">
      <p>Content of panel 2</p>
    </Panel>
  </Collapse>
);

Other packages similar to rc-collapse

react-collapse

Similar to rc-collapse, react-collapse provides components for creating collapsible content. It focuses on smooth height animations and flexibility, but it might not offer the same out-of-the-box accordion functionality.

react-accessible-accordion

This package offers a set of components to build accessible accordions in React. It emphasizes accessibility and semantic HTML structure, making it a good choice for projects that require adherence to accessibility standards. It provides a different approach compared to rc-collapse, focusing more on accessibility.

API

Collapse props

name	type	default	description
activeKey	String|Array	The first panel key	current active Panel key
className	String or object		custom className to apply
defaultActiveKey	String|Array	null	default active key
destroyInactivePanel	Boolean	false	If destroy the panel which not active, default false.
accordion	Boolean	false	accordion mode, default is null, is collapse mode
onChange	Function(key)	noop	called when collapse Panel is changed
expandIcon	(props: PanelProps) => ReactNode		specific the custom expand icon.
collapsible	'header' | 'icon' | 'disabled'	-	specify whether the panel of children is collapsible or the area of collapsible.
items	interface.ts#ItemType	-	collapse items content

If accordion is null or false, every panel can open. Opening another panel will not close any of the other panels. activeKey should be an string, if passing an array (the first item in the array will be used).

If accordion is true, only one panel can be open. Opening another panel will cause the previously opened panel to close. activeKey should be an string, if passing an array (the first item in the array will be used).

Collapse.Panel props

deprecated use items instead, will be removed in v4.0.0

name	type	default	description
header	String or node		header content of Panel
headerClass	String	' '	custom className to apply to header
showArrow	boolean	true	show arrow beside header
className	String or object		custom className to apply
style	object		custom style
openMotion	object		set the animation of open behavior, [more](https://github.com/react-component/motion). Different with v2, closed pane use a `rc-collapse-content-hidden` class to set `display: none` for hidden.
forceRender	boolean	false	forced render of content in panel, not lazy render after clicking on header
extra	String | ReactNode		Content to render in the right of the panel header
collapsible	'header' | 'icon' | 'disabled'	-	specify whether the panel be collapsible or the area of collapsible.

disabled is removed since 3.0.0, please use collapsible=disabled replace it.

key

If key is not provided, the panel's index will be used instead.

KeyBoard Event

By default, Collapse will listen onKeyDown(<3.7.0 onKeyPress) event with enter key to toggle panel's active state when collapsible is not disabled. If you want to disable this behavior, you can prevent the event from bubbling like this:

const App = () => {
  const items: CollapseProps['items'] = [
    {
      label: <input onKeyDown={(e) => e.stopPropagation()} />,
      children: 'content',
    },
    {
      label: (
        <div onKeyDown={(e) => e.stopPropagation()}>
          <CustomComponent />
        </div>
      ),
      children: 'content',
    },
    {
      label: 'title 2',
      children: 'content 2',
      collapsible: 'disabled',
    },
    {
      label: 'title 3',
      children: 'content 3',
      onItemClick: console.log,
    },
  ];

  return <Collapse items={items} />;
};
