Import
import { Accordion } from '@dnb/eufemia'
Description
The Accordion component is a combination of an accessible button (header area) and a content container.
The component is made so you can compose different parts according to your technical needs.
By default the Accordion component will animate the users events, resulting in an ending height of auto. This way the content is still responsive after the animation has ended.
Accordion provider
Use the Accordion.Provider to send along accordion properties to all nested accordions.
Accordion groups
There is the Accordion.Provider and Accordion.Group. They are technical the same, except that Accordion.Group will provide automatically an unique group id, and with that, make all the nested accordions work together and close each other.
Unexpected behavior
NB: Please try to avoid using a group, because it initiates an unexpected behavior accessibility-wise. This is because the user's interaction will trigger an action in another place, out of the current context, something some users may not expect to happen. It is an automated out-of-context UI execution.

In two columns
This is a demo of how to use a set of accordions in two Grid columns, including the correct tab order.
Accordion in columns
const items = [ <Accordion key="one" variant="filled"> <Accordion.Header> Sit amet suscipit ipsum tincidunt id? </Accordion.Header> <Accordion.Content space> <P> Sociis sapien sociosqu vel sollicitudin accumsan laoreet gravida himenaeos nostra mollis volutpat bibendum convallis cum condimentum dictumst blandit rutrum vehicula </P> </Accordion.Content> </Accordion>, <Accordion key="two" variant="filled"> <Accordion.Header> Cras eget quam eget tortor placerat viverra? </Accordion.Header> <Accordion.Content space> <P> Morbi condimentum odio ut enim vulputate, rutrum ullamcorper sem vestibulum. Ut luctus tempus leo vel finibus. Pellentesque ultrices interdum nisi, sit amet suscipit ipsum tincidunt id. Praesent sodales vel eros ut accumsan. </P> </Accordion.Content> </Accordion>, <Accordion key="three" variant="filled"> <Accordion.Header>Nam porta nec ipsum id porta</Accordion.Header> <Accordion.Content space> <P> Nam porta nec ipsum id porta. Cras eget quam eget tortor placerat viverra. </P> </Accordion.Content> </Accordion>, ] render( <> <Heading size="large">Accordion in columns</Heading> <Grid.Container columns={2} columnGap="small" rowGap="x-small"> <Grid.Item span={{ small: [1, 2], medium: [1, 1], large: [1, 1], }} > <Flex.Stack gap="x-small">{items}</Flex.Stack> </Grid.Item> <Grid.Item span={{ small: [1, 2], medium: [2, 2], large: [2, 2], }} > <Flex.Stack gap="x-small">{[...items].reverse()}</Flex.Stack> </Grid.Item> </Grid.Container> </>, )
Nested Accordions
<Accordion id="nested-accordion" title="Accordion" expanded space> <P space={0}>Content A</P> <Accordion id="nested-accordion-1" title="Accordion nested 1" space> <P space={0}>I'm nested 1</P> </Accordion> <P space={0}>Content B</P> <Accordion id="nested-accordion-2" title="Accordion nested 2" space> <P space={0}>I'm nested 2</P> </Accordion> </Accordion>
Disabled
Accordion can be disabled, though is not exactly defined what the use case is.
<Accordion expanded disabled remember_state title="Disabled (expanded)"> <P>I am expanded, but disabled, so I can't be closed</P> </Accordion> <Accordion.Provider top disabled remember_state icon="chevron_down" icon_position="right" > <Accordion title="Disabled (closed)"> <P>You can't see this text because I am disabled and closed.</P> </Accordion> </Accordion.Provider>
Variant filled
<Accordion expanded title="Accordion title" variant="filled"> <P>Accordion content</P> </Accordion> <Accordion top title="Accordion title" variant="filled"> <P>Accordion content</P> </Accordion>
Close All Accordions In A Group
You can collapse all expanded accordions by sending a ref to the collapseAllHandleRef property and calling the .current() function on your ref.
const myCollapseAllRef = React.useRef<() => void>()return (<button onClick={() => myCloseAllRef.current()}>Close all accordions</button><Accordion.Group collapseAllHandleRef={myCollapseAllRef}>{/* ... your accordions */}</Accordion.Group>)
