Description

A sp-contextual-help shows a user extra information about the state of either an adjacent component or an entire view. It explains a high-level topic about an experience and can point users to more information elsewhere.

Usage

yarn add @spectrum-web-components/contextual-help

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

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

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

import { ContextualHelp } from '@spectrum-web-components/contextual-help';

Example

<sp-contextual-help>
    <h2 slot="heading">Permission required</h2>
    Your admin must grant you permission before you can create a segment.
    <sp-link
        slot="link"
        href="https://opensource.adobe.com/spectrum-web-components/"
    >
        Request permission
    </sp-link>
</sp-contextual-help>

Help

Use variant="help" for helpful content: more detailed, in-depth guidance about a task, UI element, tool, or keyboard shortcuts. This may include an image, video, or link and should be helpful in tone.

<sp-contextual-help variant="help">
    <h2 slot="heading">What is a segment?</h2>
    Segments identify who your visitors are, what devices and services they use,
    where they navigate from, and much more.
    <sp-link
        slot="link"
        href="https://opensource.adobe.com/spectrum-web-components/"
    >
        Learn more about segments
    </sp-link>
</sp-contextual-help>

Placement

By default a sp-contextual-help will render its popover at the bottom-start position. This can be customized using the placement attribute and supports all the placement options an overlay-trigger component supports.

<sp-contextual-help placement="top-start">
    <h2 slot="heading">Permission required</h2>
    Your admin must grant you permission before you can create a segment.
    <sp-link
        slot="link"
        href="https://opensource.adobe.com/spectrum-web-components/"
    >
        Request permission
    </sp-link>
</sp-contextual-help>

Custom max width

Contextual help allows for a custom maximum width to be set using the --mod-spectrum-contextual-help-popover-maximum-width custom property.

Note: Maximum width should not be less than 100px.

<sp-contextual-help
    style="--mod-spectrum-contextual-help-popover-maximum-width: 200px;"
>
    <h2 slot="heading">Custom max width</h2>
    This is a test of the contextual help component with a custom max width of
    200px.
</sp-contextual-help>

Events

sp-contextual-help does not fire any events of its own. You can listen, however, for the sp-open and sp-closed events which are fired when the popover opens or closes.

Accessibility

Given that the trigger is an icon-only sp-action-button, it is important to provide an accessible name for it, so that it can be properly announced by screen readers. By default, the sp-contextual-help uses an aria-label property with either "Informations" or "Help" as values, depending on the component's variant. You can customize this using the label attribute.

When providing headings using the heading slot, make sure to provide actual heading elements such as h1, h2, h3 ... or use the role="heading" attribute.
