Description #

sp-dialog-base accepts slotted dialog content (often an <sp-dialog>) and presents that content in a container that is animated into place when toggling the open attribute. In concert with the Overlay API or Overlay Trigger, the provided dialog content will be displayed over the rest of the page. Leverage the interaction = modal and receivesFocus = 'auto' settings in the Overlay API to ensure that focus is thrown into the dialog content when opened and that the tab order will be trapped within it while open.

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

import { DialogBase } from '@spectrum-web-components/dialog';

Example #

<overlay-trigger type="modal">
    <sp-dialog-base underlay slot="click-content">
        <sp-dialog size="s">
            <h2 slot="heading">A thing is about to happen</h2>
            <p>Something that might happen a lot is about to happen.</p>
            <p>
                The click events for the "OK" button are bound to the story not
                to the components in specific.
            </p>
            <sp-button
                variant="secondary"
                treatment="fill"
                slot="button"
                onclick="this.dispatchEvent(new Event('close', { bubbles: true, composed: true }));"
            >
                Ok
            </sp-button>
            <sp-checkbox slot="footer">Don't show me this again</sp-checkbox>
        </sp-dialog>
    </sp-dialog-base>
    <sp-button slot="trigger" variant="primary">Toggle Dialog</sp-button>
</overlay-trigger>

Dialog #

sp-dialog-base expects a single slotted child element to play the role of the dialog that it will deliver within your application. When leveraging it as a base class be sure to customize the dialog getter to ensure that it acquires the appropriate element for your use case in order to correctly pass focus into your content when the dialog is opened.
