// Automatically shows on init if cookie isn't set $('.cookie.nag') .nag({ key : 'accepts-cookies', value : true }) ;

// Clears cookie so nag shows again $('.cookie.nag') .nag('clear') ;


Nags are used to present a user with a one time message which will persist until a user acknowledges the message. This can be used for providing notices like the site's use of cookies, an important change to a site like a security breach.

Fomantic's nag component provides built in options for ensuring a nag is only displayed once. You can trigger an API endpoint on dismissal, in order to store a value in your database, or you can use localstorage, sessionstorage or cookie value to make sure that a particular computer does not receive the nag again.

Initializing a Nag
