Important notes:
This page is archived information that is not up-to-date.
Information about EOWG closing is in the 19 September 2024 blog post: Accessibility education and outreach: Another milestone in W3C's 30-year history and evolution.
This Wiki page was edited by participants of the EOWG. It does not necessarily represent consensus and it may have incorrect information or information that is not supported by other Working Group participants, WAI, or W3C. It may also have some very useful information.
Currently Expand/Collapse is using a relatively complicated JavaScript – it might be worth looking into the use cases and see if we can come by using a standard HTML details element:
<details><summary></summary></details>
Details is well supported, and a polyfill exists for browsers without support.
