Question

In the drop-down menu there is a list of countries in English, when you change the language, the list should change, for example, to Russian.

Answer 1

The list of countries is content. And the server part should be engaged in the translation of content (no matter what widget you use). Use standard internationalization tools for this.

Answer 2

When you change the language, the page usually reloads and the url changes. This means that the page is re-formed in php, so you just need to submit data to the widget depending on the current language.
