Hello,  
I would like what this loop return only the category of the page.categories.  
So I try this assign -\> site.products[page.categories]  
but no result. I don’t find a filter to do this condition

Thanks for and advice

```
 `---

```

## layout: default

# {{ page.categories | capitalize }}

{% assign products = site.products[page.categories] %} {% for product in products %} - {{ product.name }} {% for cat\_name in product.categories %} {{ cat\_name }} {% endfor %} 
 {% else %} 

Error -- Product empty

 {% endfor %}
