@spectrum-web-components/popover

Overview

An <sp-popover> is used to display transient content (menus, options, additional actions etc.) and appears when clicking/tapping on a source (tools, buttons, etc.) It stands out via its visual style (stroke and drop shadow) and floats on top of the rest of the interface. This component does not implement the actual overlay behavior and interactions. This is handled by the Overlay system.

Usage

yarn add @spectrum-web-components/popover

Import the side effectful registration of <sp-popover> via:

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

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

import { Popover } from '@spectrum-web-components/popover';

Anatomy

<div
    style="
        position: relative;
        height: 100px;
    "
>
    <sp-popover open>
        Cupcake ipsum dolor sit amet jelly beans. Chocolate jelly caramels.
    </sp-popover>
</div>

Options

Default with no tip

Default popover with no tip and no placement. Popovers will fill up the space of their containing element by default. The default popover has no padding.

<div
    style="
        position: relative;
        height: 180px;
        max-width: 320px;
    "
>
    <sp-popover variant="default" open>
        <h2>Popover title</h2>
        <p>
            Cupcake ipsum dolor sit amet jelly beans. Chocolate jelly caramels.
            Icing soufflé chupa chups donut cheesecake. Jelly-o chocolate cake
            sweet roll cake danish candy biscuit halvah
        </p>
    </sp-popover>
</div>

Dialog popovers

To apply a managed amount of padding within your <sp-popover>, you may choose to wrap your slotted content in an <sp-dialog> element, as seen below:

<div
    style="
        position: relative;
        height: 250px;
        max-width: 320px;
    "
>
    <sp-popover open>
        <sp-dialog>
            <h3 slot="heading">Popover title</h3>
            Cupcake ipsum dolor sit amet jelly beans. Chocolate jelly caramels.
            Icing soufflé chupa chups donut cheesecake. Jelly-o chocolate cake
            sweet roll cake danish candy biscuit halvah
        </sp-dialog>
    </sp-popover>
</div>

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.
