Accordion

<auro-accordion> is a HTML custom element for the purpose of toggling the visibility of large content section by clicking on a smaller trigger element.

Use Cases

The <auro-accordion> element should be used in situations where users may:

• Hide/show long sub-content based on headline trigger
• Use is for in-page content only when excessive content length is distracting to the specific experience

Install

$ npm i @aurodesignsystem/auro-accordion

Define Dependency in Project

Defining the dependency within each project that is using the <auro-accordion> component.

import "@aurodesignsystem/auro-accordion";

Use CDN

In cases where the project is not able to process JS assets, there are pre-processed assets available for use. Legacy browsers such as IE11 are no longer supported.

<script type="module" src="https://cdn.jsdelivr.net/npm/@aurodesignsystem/auro-accordion@latest/+esm"></script>

Basic Example

<auro-accordion>
  <span slot="trigger">Trigger</span>
  <p>
    Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
  </p>
  <p>
    Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
  </p>
  <p>
    Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur.
  </p>
  <p>
    Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.
  </p>
</auro-accordion>

Custom Component Registration for Version Management

There are two key parts to every Auro component: the class and the custom element definition. The class defines the component’s behavior, while the custom element registers it under a specific name so it can be used in HTML.

When you install the component as described on the Install page, the class is imported automatically, and the component is registered globally for you.

However, if you need to load multiple versions of the same component on a single page (for example, when two projects depend on different versions), you can manually register the class under a custom element name to avoid conflicts.

You can do this by importing only the component class and using the register(name) method with a unique name:

// Import the class only
import { AuroAccordion, AuroAccordionGroup } from '@aurodesignsystem/auro-accordion/class';

// Register with a custom name if desired
AuroAccordion.register('custom-accordion');
AuroAccordionGroup.register('custom-accordion-group');

This will create a new custom element <custom-accordion> and <custom-accordion-group> that behaves exactly like <auro-accordion> and <auro-accordion-group>, allowing both sets of components to coexist on the same page without interfering with each other.
