Interface design for multilingual forms

Imagine a multilingual website whose editors have to add information in many languages ​​at once.

Moreover, they spend most of their time working with forms.

It is necessary to make their work as convenient as possible.



Forms can have both language-dependent and language-independent fields.

The latter, of course, do not need translations.

But how to present language-dependent fields to editors - this is what I want to discuss.



A prerequisite is that all language versions must be edited on one page.

At the moment I see the following two options:



1. Switching languages ​​in the form (for example, through tabs). Thus, we present a separate form for each language.



2. Switching the form fields and filling in all the language versions of each field separately.



Both versions from different points of view seem convenient, depending on the number of fields and languages.

Perhaps there are other options for the presentation of multilingual forms?

Share, please, advice, who knows.
