The CMS Questions

Is it possible to automatically set the page slug to the page title of the respective language when using an “article” template?

Example:
DE: http://domain.xx/das-ist-mein-artikel
EN: http://domain.xx/en/this-is-my-article

You could try to add a slug programmatically via a page.update:after hook.
