Sites with 2 or more languages that use the wpml extension can enjoy the accessibility component depending on the changing language.
First, sign up for wordrpress accessibility to add the site in its main language, get the code to embed wpml and embed in the site, as detailed here.
Automatically when the user clicks the language switch button on the site, the component will also change to the desired language.
You will also of course be able to choose where the component will be located in any language as described here.
Once implemented, when you want to define unique names for the various menus as detailed here, you must do this first on the existing site in your account in the system (in the main language) and then on the management panel add the site in the second language and perform the menu setup there as well.
