The Bridge theme is bundled with the WPBakery Page Builder (former Visual Composer) and they are both compatible with WPML. This means that you use the page builder to create your pages and then translate only the texts inside. Additionally, you can easily translate the theme's Portfolio pages, categories, and texts coming from the Bridge theme. If you use Bridge to create an online store, use the WooCommerce Multilingual add-on to translate WooCommerce elements like Products, and Product Categories.
Here you will find WPML contractors who can help you build multilingual sites based on bridge and WPML. Use the search to find contractors who are right for your project and send them a message to get started.
