Categories are used to organize vendors into groups. You can create as many categories as you need and edit the default ones. The default categories are: * Essential * Analytics * Marketing * Personalization Categories A category becomes active when it contains an active service or storage items. Only active categories are shown to visitors in the banner. ## What are vendors? Storage items set by a vendor/service can be grouped together. Services must be associated with a category and each service will have a toggle inside its category section to allow users to opt-in or opt-out of the service. You can then use the services attribute to [block scripts until consent](/block-scripts-cookies). CookieChimp offers a vendor library of popular services that contain storage items set by the service. Simply select the ones used in your site and add. Vendor Library If you are using a service that is not in our vendor library, you can create a service manually. ## What are storage items? Storage items can be of three types: * Cookie * Local Storage * Session Storage Storage items can be grouped together into a service or be added to a category directly. Cookie
