We’re always adding new widgets, and you can also [create your own](https://www.netlifycms.org/docs/custom-widgets)!

(No login required: click the login button and the CMS will open.) You can refer to the demo [configuration code](https://github.com/netlify/netlify-cms/blob/master/example/config.yml#L60) to see how each field was configured.
