In today's globalized world, reaching audiences in their native language can make all the difference. We're excited to introduce a new feature that helps you do just that: **Language-Based Shelves** and **Language Filter** capabilities for your storefront.

## **Language-Based Shelves**

This new filter allows you to easily organize your products based on language content. This means you can create dedicated shelves for the languages your audience speaks, with support for over **184 languages**. If you want to target Spanish-speaking customers, for instance, just create an "Español" shelf to display all relevant content.

The language filter empowers users to discover products in specific languages. It's perfect for multilingual platforms looking to streamline content searchability. Simply filter content using ISO 639-1 language codes, covering languages like:

- **English** (`en`)
- **Spanish** (`es`)
- **Portuguese** (`pt`)
- **German** (`de`)
- **French** (`fr`)
- **Chinese** (`zh`)
- **Japanese** (`ja`)
- ... and **174+ more**!

### **Usage Examples:**

- To filter for Spanish content: `/library/filter?language=es`
- Combine with other filters like file type and year: `/library/filter?file_type=pdf&language=en&years=2024`
- Use this filter when creating the menu at the header of your store

Incorporate these new filters to improve the accessibility and relevancy of your products across diverse language communities. Start creating language-specific experiences today!
