All notable changes to this project are documented in this file. This project adheres to Semantic Versioning.
A sort-of breaking change which updates the default behavior regarding
allowMultipleExpanded and allowZeroExpanded. They both now default to
true.
This is based on advice from NNG, as well as Springload's views on accordion usability.
From this version onwards:
- to disable allowing more than one accordion panel to be open at once, you
must explicitly set
allowMultipleExpanded={false} - to disable collapsing all accordion panels, you must explicitly set
allowZeroExpanded={false}
React Accessible Accordion now supports React 18 with its out-of-order streaming feature.
The new out-of-order streaming feature required using React 18's
useId hook. This
affects the DOM ids that RAA generates, changing from accordion__heading-raa-0
(React 16 and 17) to accordion__heading-:r0: (React 18). Although this change
shouldn't affect most users, if you have any code that selects ids with DOM APIs
such as document.querySelector() then the : characters will need escaping
with \\ eg. document.querySelector('#accordion__heading-\\:r0\\:').
When using older versions of React 16 or 17 the same DOM ids will be generated.
Because of this change in behaviour this is a major version upgrade.
Making role="region" optional on panels.
The new behaviour has no role="region" by default, and developers can opt-in
using the region prop as <AccordionItemPanel region>.
The previous behaviour had every panel as a role="region" which created an
excessive amount of regions for the screen reader.
Because of this change in behaviour this is a major version upgrade.
- Bundle size reduction
- Use
console.errorwhen provided with invalid HTML5 ids
- Use
hiddencapabilities rather than something needing custom css everywhere.
- New
AccordionItemproperty:dangerouslySetExpandedenabling external control of the expansion. - New
AccordionItemproperty:activeClassNameto support expansion-related styles
hiddensupport on Microsoft Edge
- Refactor away
Array.prototype.findIndexin favour ofArray.prototype.indexOfto reinstate IE 11 support without use of a polyfill (#237, #224).
This release is the culmination of a massive amount of work, resulting in some new features and significantly stronger and more reliable WAI ARIA spec compliance. Notably, the project has been migrated from Flow to Typescript, and a full accessibility audit has been performed - revealing a few holes in our compliance which have now been entirely addressed.
Thanks to everyone who has contributed to this release - and not just those who have written code. Contribution by way of issues relating to spec compliance, pull-request commentary, advice and assistance is all greatly appreciated. Thanks also to the patient users who have endured an extended period without a release while we made sure to get this 100% right! Release cadence should return to normal again now.
-
Rename all of your
AccordionItemTitlecomponents toAccordionItemHeadingand then nest anAccordionItemButtondirectly inside of each one. Note that in order for your Accordion to remain spec-compliant, you may not put any other children insideAccordionItemHeading.// Before: import { AccordionItemTitle } from 'react-accessible-accordion'; const headingBefore = <AccordionItemTitle>Foo</AccordionItemTitle>;
// After: import { AcccordionItemHeading, AccordionItemButton, } from 'react-accessible-accordion'; const headingAfter = ( <AccordionItemHeading> <AccordionItemButton>Foo</AccordionItemButton> </AccordionItemHeading> );
-
Rename all of your
AccordionItemBodycomponents toAccordionItemPanel.// Before: import { AccordionItemBody } from 'react-accessible-accordion'; const panelBefore = ( <AccordionItemBody> Voluptate elit eiusmod laborum proident esse officia dolor laboris laboris amet nulla officia cillum. </AccordionItemBody> );
// After: import { AccordionItemPanel } from 'react-accessible-accordion'; const panelAfter = ( <AccordionItemPanel> Voluptate elit eiusmod laborum proident esse officia dolor laboris laboris amet nulla officia cillum. </AccordionItemPanel> );
-
Remove all instances of
hideBodyClassName. This prop is no longer valid, asAccordionItemPanelcomponents are now hidden without additional styling. If you must have a differentclassNameprop when an item is collapsed, then you may leverage the newAccordionItemStatecomponent.// Before import { AccordionItemPanel } from 'react-accessible-accordion'; const panelBefore = ( <AccordionItemPanel className="foo" hideBodyClassName="foo--hidden" /> );
// After: import { AccordionItemPanel, AccordionItemState, } from 'react-accessible-accordion'; const panelAfter = ( <AccordionItemState> {({ expanded }) => ( <AccordionItemPanel className={expanded ? 'foo' : 'foo foo--hidden'} /> )} </AccordionItemState> );
-
Remove all instances of
AccordionItem’sexpandedprop and instead useAccordion’spreExpandedprop. Note that this means that ‘controlled’ accordions are no longer a supported pattern. Please raise an issue if you have a use-case which calls for the ability to manually control expanded state.// Before import { Accordion, AccordionItem } from 'react-accessible-accordion'; const accordionBefore = ( <Accordion> <AccordionItem expanded /> </Accordion> );
// After: import { Accordion, AccordionItem } from 'react-accessible-accordion'; const accordionAfter = ( <Accordion preExpanded={['foo']}> <AccordionItem uuid="foo" /> </Accordion> );
-
Remove all instances of
Accordion’saccordionprop. Instead, use a combination ofallowZeroExpandedandallowMultipleExpandedprops to suit your requirements. If you were not explicitly settingaccordiontofalsethen you probably are not required to make any changes here.// Before import { Accordion } from 'react-accessible-accordion'; const accordionBefore = <Accordion accordion={false} />;
// After: import { Accordion } from 'react-accessible-accordion'; const accordionAfter = <Accordion allowMultipleExpanded />;

- Upgrade all dev-dependencies except the eslint configs.
- Replace snapshot tests with explicit assertions in AccordionItemBody and AccordionItemTitle.
- Add specific assertions to tests in accordionStore.
- Minor syntax change in AccordionItemBody
Version 2.0 represents a total refactor, with a new context-based approach which should make this library more flexible, more maintainable and more comprehensively testable.
As this is a major release, users should expect some breaking changes - though
they should be limited to the removal of the activeItems prop (read more
below).
- Exports
resetNextId(#41).
- Defect where controlled components' props were overridden by React.Children.map (#33).
- Defect where accordion crashed with unexpected
childrentypes (#45). - Defect where React Accessible Accordion's components could not be extended.
- Defect where the
childrenofAccordionorAccordionItemcould not be arbitrary. - Defect where
AccordionItemhad to be a child ofAccordion(as opposed to to an arbitrary-level descendant). - Defect where
AccordionItemBodyandAccordionItemTitlehad to be children ofAccordionItem(as opposed to arbitrary-level descendants).
- 🚨 Breaking change 🚨
activeItemsproperty is no longer supported.
Control at the Accordion level (via the activeItems prop) and
AccordionItem level (via the expanded prop) fought against one another, and
choosing which control mechanism to give preference to would have been an
arbitrary decision - and whichever way we went, we would have had test cases
which demonstrated unusual/unpredictable behaviour. The activeItems mechanism
was the obvious one to remove - it was arguably the "less React-y way", and we
considered it more of a convenience than a feature. Crucially though, it fought
too hard against the new architecture of the library, and keeping it would have
prevented us enabling lots of other new features or resolving some of the issues
that our users had raised.
If you're currently using activeItems, you're upgrade path might look like this:
const items = ['Foo', 'Bar'];
const activeItems = [0];
return (
- <Accordion activeItems={activeItems} />
+ <Accordion />
{activeItems.forEach((item, i) => (
- <AccordionItem key={item}>{item}</AccordionItem>
+ <AccordionItem key={item} expanded={activeItems.includes(i)}>{item}</AccordionItem>
)}
</Accordion>
);Please don't hesitate to reach out to one of the maintainers (or raise an issue) if you're having trouble upgrading - we're happy to help!
