Hi Kris,
Thanks for reaching out and thanks for using Crio Pro WordPress theme!
For your situation a plugin like WPML would be best to handle your task of adding multiple languages to your WordPress site. WPML comes in Multilingual blog and Multilingual CMS licensing plans. You’ll need the multilingual CMS plan for eCommerce, page builder support, custom fields, managing translation teams, and some other features.
It comes with an easy to use interface to add translations and manage multilingual content across your website. WPML supports all post types, taxonomies, custom fields, and strings generated by your WordPress themes and plugins.
I hope this helps. Please reach back out if you have any other questions for us.
