@spectrum-web-components/accordion

Description

The <sp-accordion> element contains a list of items that can be expanded or collapsed to reveal additional content or information associated with each item. There can be zero expanded items, exactly one expanded item, or more than one item expanded at a time, depending on the configuration. This list of items is defined by child <sp-accordion-item> elements that are targetted to the default slot of their <sp-accordion> parent.

Usage

yarn add @spectrum-web-components/accordion

Import the side effectful registration of <sp-accordion> and <sp-accordion-item> via:

import '@spectrum-web-components/accordion/sp-accordion.js';
import '@spectrum-web-components/accordion/sp-accordion-item.js';

When looking to leverage the Accordion and AccordionItem base class as a type and/or for extension purposes, do so via:

import { Accordion, AccordionItem } from '@spectrum-web-components/accordion';

Changelog

1.7.0 (2025-06-11)

Minor Changes

sp-overlay: Fixed : Overlays (like pickers and action menus) were incorrectly closing when scrolling occurred within components. The fix ensures the handleScroll method in OverlayStack only responds to document/body scrolling events and ignores component-level scrolling events, which was the original intention.

sp-card: Fixed: On mobile Chrome (both Android and iOS), scrolling on sp-card components would inadvertently trigger click events. This was caused by the timing-based click detection (200ms threshold) in the pointer event handling, which could misinterpret quick scrolls as clicks. This issue did not affect Safari on mobile devices.

sp-action-button: - Fixed : Action buttons with href attributes now properly detects modifier keys and skips the proxy click, allowing only native browser behavior to proceed.

Patch Changes

sp-styles: Remove unnecessary system theme references to reduce complexity for components that don't need the additional mapping layer.

sp-card: - Fixed: sp-card component relies on sp-popover for certain toggle interactive behaviors, but this dependency was missing from its dependency tree.

sp-menu: Fixes: Icons in menu stories weren't properly responding to theme changes when used in functional story components. Switching to class-based LitElement components ensures proper component lifecycle hooks and shadow DOM context for icon initialization and theme integration.

sp-tabs: Added @spectrum-web-components/action-button as a dependency for Tabs as its used in the direction button.

sp-split-view: Added @spectrum-web-components/shared dependency in splitview since it uses ranDomId from the shared package

sp-textfield: Replace deprecated word-break: break-word with overflow-wrap: break-word to align with modern CSS standards and improve cross-browser compatibility. This property was deprecated in Chrome 44 (July 2015) in favor of the standardized overflow-wrap property.
