Polylang - Customizer & Theme Ooptions
You can translate strings in Polylang under WP Dash / Languages / String Translations, however, Polylang by default does not provide access to the Customizer settings or the theme options, so if you wanted to have a different footer widget setting per language, you'll need a script to help with that. We recommend adding the following script to your child theme.
Download and place the files inside your child theme folder https://github.com/ryanlabelle/customizer-polylang
It should look like this: https://cl.ly/3n151o1f2y12
include( STYLESHEETPATH . '/customizer-polylang.php');
It should look like this: https://cl.ly/1c1x2p1b2233
That should be it. :)
At the top of your cusotmizer window, you should see a language dropdown.
If you run into any issues, please let us know. Happy to help.
