useDismiss
Controls the dismissal and visibility state of an InfoBanner.
By default stores the dismissal state in React state. If given the persistToCookie
option, it will persist the dismissal state across page loads in a session cookie. You may pass a function returning a boolean, for example persistToCookie={checkFunctionalCookieConsent}
.
If a key
is given, the dismissal will be valid globally on the entire domain under that key. This is useful if you have multiple pages showing the same InfoBanner or multiple dismissable InfoBanners on the same page. Use a globally unique key, prefixed with your application name. If no key
is given the dismissal will be valid for any banner on the same exact path.
const DismissableInfoBanner = ({ children }) => {
const { dismiss, visible } = useDismiss();
return visible ? (
<InfoBanner onDismiss={dismiss}>{children}</InfoBanner>
) : (
'Dismissed'
);
};
render(<DismissableInfoBanner>Info message</DismissableInfoBanner>);
| Name | Description | Type | Default Value |
| ----------------- | -------------------------------------------- | ---------------------------- | ------------- |
| persistToCookie
| Enable persisting dismissal state in cookie. | boolean
or () => boolean
| false
|
| key
| Unique key for dismissal state in cookie. | string
| undefined
