Once you configure languages in the Localization settings of your project, you will be able to choose a language variant for your content in the content list or when editing a content item.
Switching languages in the content list
To switch to a different language in the content list, click the language switcher in the top right corner and select a language.
Switching languages while editing content
To change the language variant of the currently edited content item, use the language switcher next to the content item's title.
Note: If you switch to a language variant in which the content item doesn't exist yet, Kentico Cloud automatically creates an empty draft in the selected language. See Translating content items for more information.
