function BasicExample() {
  return (
    <Accordion defaultActiveKey="0">
      <Accordion.Item eventKey="0">

Fully Collapsed State

If you want your Accordion to start in a fully-collapsed state, then simply don't pass in a defaultActiveKey prop to Accordion.

import Accordion from 'react-bootstrap/Accordion';

function AllCollapseExample() {
  return (
    <Accordion>
      <Accordion.Item eventKey="0">
        <Accordion.Header>Accordion Item #1</Accordion.Header>

    </Accordion>
  );

export default AllCollapseExample;

Flush

Add flush to remove the default background-color, some borders, and some rounded corners to render accordions edge-to-edge with their parent container.

import Accordion from 'react-bootstrap/Accordion';

function FlushExample() {
  return (
    <Accordion defaultActiveKey="0" flush>

Always open

You can make accordion items stay open when another item is opened by using the alwaysOpen prop. If you're looking to control the component, you must use an array of strings for activeKey or defaultActiveKey.

import Accordion from 'react-bootstrap/Accordion';

function AlwaysOpenExample() {
  return (
    <Accordion defaultActiveKey={['0']} alwaysOpen>
      <Accordion.Item eventKey="0">
        <Accordion.Header>Accordion Item #1</Accordion.Header>
        <Accordion.Body>
          Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do
          eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad
          minim veniam, quis nostrud exercitation ullamco laboris nisi ut
          aliquip ex ea commodo consequat. Duis aute irure dolor in
          reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla
          pariatur. Excepteur sint occaecat cupidatat non proident, sunt in
          culpa qui officia deserunt mollit anim id est laborum.

Custom Accordions

You can still create card-based accordions like those in Bootstrap 4. You can hook into the Accordion toggle functionality via useAccordionButton to make custom toggle components.

Custom Toggle

import Accordion from 'react-bootstrap/Accordion';
import { useAccordionButton } from 'react-bootstrap/AccordionButton';
import Card from 'react-bootstrap/Card';

function CustomToggle({ children, eventKey }) {
  const decoratedOnClick = useAccordionButton(eventKey, () =>
    console.log('totally custom!'),
  );

  return (
    <button
      type="button"
      style={{ backgroundColor: 'pink' }}
      onClick={decoratedOnClick}
    >
      {children}
    </button>
  );
}

function Example() {
  return (
    <Accordion defaultActiveKey="0">
      <Card>
        <Card.Header>
          <CustomToggle eventKey="0">Click me!</CustomToggle>
        </Card.Header>
        <Accordion.Collapse eventKey="0">
          <Card.Body>Hello! I'm the body</Card.Body>
        </Accordion.Collapse>
      </Card>
      <Card>
        <Card.Header>
          <CustomToggle eventKey="1">Click me!</CustomToggle>
        </Card.Header>
        <Accordion.Collapse eventKey="1">
          <Card.Body>Hello! I'm another body</Card.Body>
        </Accordion.Collapse>
      </Card>
    </Accordion>
  );
}

render(<Example />);

import Accordion from 'react-bootstrap/Accordion';
import { useAccordionButton } from 'react-bootstrap/AccordionButton';
import Card from 'react-bootstrap/Card';

function CustomToggle({ children, eventKey }) {
  const decoratedOnClick = useAccordionButton(eventKey, () =>
    console.log('totally custom!'),
  );

  return (
    <button
      type="button"
      style={{ backgroundColor: 'pink' }}
      onClick={decoratedOnClick}
    >
      {children}
    </button>
  );
}

function Example() {
  return (
    <Accordion defaultActiveKey="0">
      <Card>
        <Card.Header>
          <CustomToggle eventKey="0">Click me!</CustomToggle>
        </Card.Header>
        <Accordion.Collapse eventKey="0">
          <Card.Body>Hello! I'm the body</Card.Body>
        </Accordion.Collapse>
      </Card>
      <Card>
        <Card.Header>
          <CustomToggle eventKey="1">Click me!</CustomToggle>
        </Card.Header>
        <Accordion.Collapse eventKey="1">
          <Card.Body>Hello! I'm another body</Card.Body>
        </Accordion.Collapse>
      </Card>
    </Accordion>
  );
}

render(<Example />);

Custom Toggle with Expansion Awareness

You may wish to have different styles for the toggle if it's associated section is expanded, this can be achieved with a custom toggle that is context aware and also takes advantage of the useAccordionButton hook.

import Accordion from 'react-bootstrap/Accordion';
import { useAccordionButton } from 'react-bootstrap/AccordionButton';
import Card from 'react-bootstrap/Card';

function ContextAwareToggle({ children, eventKey, callback }) {
  const { activeEventKey } = useContext(AccordionContext);

  const decoratedOnClick = useAccordionButton(
    eventKey,
    () => callback && callback(eventKey),
  );

  const isCurrentEventKey = activeEventKey === eventKey;

  return (
    <button
      type="button"
      style={{ backgroundColor: isCurrentEventKey ? 'pink' : 'lavender' }}
      onClick={decoratedOnClick}
    >
      {children}
    </button>
  );
}

function Example() {
  return (
    <Accordion defaultActiveKey="0">
      <Card>
        <Card.Header>
          <ContextAwareToggle eventKey="0">Click me!</ContextAwareToggle>
        </Card.Header>
        <Accordion.Collapse eventKey="0">
          <Card.Body>Hello! I'm the body</Card.Body>
        </Accordion.Collapse>
      </Card>
      <Card>
        <Card.Header>
          <ContextAwareToggle eventKey="1">Click me!</ContextAwareToggle>
        </Card.Header>
        <Accordion.Collapse eventKey="1">
          <Card.Body>Hello! I'm another body</Card.Body>
        </Accordion.Collapse>
      </Card>
    </Accordion>
  );
}

render(<Example />);

import Accordion from 'react-bootstrap/Accordion';
import { useAccordionButton } from 'react-bootstrap/AccordionButton';
import Card from 'react-bootstrap/Card';

function ContextAwareToggle({ children, eventKey, callback }) {
  const { activeEventKey } = useContext(AccordionContext);

  const decoratedOnClick = useAccordionButton(

    () => callback && callback(eventKey),
  );

  const isCurrentEventKey = activeEventKey === eventKey;

  return (
    <button
      type="button"
      style={{ backgroundColor: isCurrentEventKey ? 'pink' : 'lavender' }}
      onClick={decoratedOnClick}
    >
      {children}
    </button>
  );
}

function Example() {
  return (
    <Accordion defaultActiveKey="0">

        </Card.Header>
        <Accordion.Collapse eventKey="0">
          <Card.Body>Hello! I'm the body</Card.Body>
        </Accordion.Collapse>
      </Card>
      <Card>
        <Card.Header>
