Import#

Chakra UI exports 5 accordion-related components.

Accordion: The wrapper that uses cloneElement to pass props to AccordionItem children.
AccordionItem: A single accordion item.
AccordionButton: The button that toggles the expand/collapse state of the accordion item. This button must be wrapped in an element with role heading.
AccordionPanel: The container for the details to be revealed.
AccordionIcon: A chevron-down icon that rotates based on the expanded/collapsed state

import {
  Accordion,
  AccordionItem,
  AccordionButton,
  AccordionPanel,
  AccordionIcon,
} from '@chakra-ui/react';

Usage#

By default, only one item may be expanded and it can only be collapsed again by expanding another.

Accordion now supports keyboard navigation between accordion buttons. Pressing the up and down arrow keys will move focus between accordion buttons.

<Accordion>
  <AccordionItem>
    <h2>
      <AccordionButton>
        <Box flex="1" textAlign="left">
          Section 1 title
        </Box>
        <AccordionIcon />
      </AccordionButton>
    </h2>
    <AccordionPanel pb={4}>
      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.
    </AccordionPanel>
  </AccordionItem>

  <AccordionItem>
    <h2>
      <AccordionButton>
        <Box flex="1" textAlign="left">
          Section 2 title
        </Box>
        <AccordionIcon />
      </AccordionButton>
    </h2>
    <AccordionPanel pb={4}>
      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.
    </AccordionPanel>
  </AccordionItem>
</Accordion>

Expand multiple items at once#

If you set allowMultiple to true then the accordion will permit multiple items to be expanded at once.

If you pass this prop, ensure that the index or defaultIndex prop is an array.

<Accordion defaultIndex={[0]} allowMultiple>
  <AccordionItem>
    <h2>
      <AccordionButton>
        <Box flex="1" textAlign="left">
          Section 1 title
        </Box>
        <AccordionIcon />
      </AccordionButton>
    </h2>
    <AccordionPanel pb={4}>
      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.
    </AccordionPanel>
  </AccordionItem>

  <AccordionItem>
    <h2>
      <AccordionButton>
        <Box flex="1" textAlign="left">
          Section 2 title
        </Box>
        <AccordionIcon />
      </AccordionButton>
    </h2>
    <AccordionPanel pb={4}>
      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.
    </AccordionPanel>
  </AccordionItem>
</Accordion>

Toggle each accordion item#

If you set allowToggle to true, any expanded item may be collapsed again.

<Accordion allowToggle>
  <AccordionItem>
    <h2>
      <AccordionButton>
        <Box flex="1" textAlign="left">
          Section 1 title
        </Box>
        <AccordionIcon />
      </AccordionButton>
    </h2>
    <AccordionPanel pb={4}>
      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.
    </AccordionPanel>
  </AccordionItem>

  <AccordionItem>
    <h2>
      <AccordionButton>
        <Box flex="1" textAlign="left">
          Section 2 title
        </Box>
        <AccordionIcon />
      </AccordionButton>
    </h2>
    <AccordionPanel pb={4}>
      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.
    </AccordionPanel>
  </AccordionItem>
</Accordion>

Styling the expanded state#

The AccordionButton component has aria-expanded set to true or false depending on the state of the AccordionItem. Use the style prop _expanded to style this state.

<Accordion>
  <AccordionItem>
    <h2>
      <AccordionButton _expanded={{ bg: 'tomato', color: 'white' }}>
        <Box flex="1" textAlign="left">
          Click me to see a different style
        </Box>
        <AccordionIcon />
      </AccordionButton>
    </h2>
    <AccordionPanel>
      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.
    </AccordionPanel>
  </AccordionItem>
</Accordion>

Accessing the internal state#

If you need access to the internal state of each accordion item, you can use a render prop. It provides 2 internal state props: isExpanded and isDisabled.

<Accordion allowMultiple>
  <AccordionItem>
    <h2>
      <AccordionButton>
        <Box flex="1" textAlign="left">
          Section 1 title
        </Box>
        <AccordionIcon />
      </AccordionButton>
    </h2>
    <AccordionPanel pb={4}>
      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.
    </AccordionPanel>
  </AccordionItem>

  <AccordionItem>
    {({ isExpanded }) => (
      <>
        <h2>
          <AccordionButton>
            <Box flex="1" textAlign="left">
              Section 2 title
            </Box>
            {isExpanded ? (
              <MinusIcon fontSize="12px" />
            ) : (
              <AddIcon fontSize="12px" />
            )}
          </AccordionButton>
        </h2>
        <AccordionPanel pb={4}>
          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.
        </AccordionPanel>
