Collapse/Accordion

Notes on Implementation

We implement Bootstrap’s Accordion component styles from Bootstrap 5. Bootstrap 4’s accordion implementation (an example within their Collapse component) is missing the necessary styles (such as the icon to indicate it can be opened). However, the functionality from Bootstrap 4’s Collapse component is used.

Accessibility Notes

In the example below, taken from Bootstrap, we remove the data-parent="#selector" from each section so that more than one section can be opened at a time. We also add an arrow indicating that this section can be expanded.

This interactive component should be a <button> wrapped within a heading element. The accessible name of the heading should be unique and make sense out of context. The heading level should chosen to appropriately follow the structure on the page. And the state must be included using the aria-expanded attribute. Follow the example below.
