# Using custom attributes in menus and taxonomy archives
|
|||
|
|
|
|||
|
|
Attributes that can be used for the layered nav are a custom taxonomy, which means you can display them in menus, or display products by attributes. This requires some work on your part, and archives must be enabled.
|
|||
|
|
|
|||
|
|

# Register the taxonomy for menus
|
|||
|
|
|
|||
|
|
When registering taxonomies for your custom attributes, WooCommerce calls the following hook:
|
|||
|
|
|
|||
|
|
```php
|
|||
|
|
$show_in_nav_menus = apply_filters('woocommerce_attribute_show_in_nav_menus', false, $name);
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
So, for example, if your attribute slug was `size` you would do the following to register it for menus:
|
|||
|
|
|
|||
|
|
```php
|
|||
|
|
add_filter('woocommerce_attribute_show_in_nav_menus', 'wc_reg_for_menus', 1, 2);
|
|||
|
|
|
|||
|
|
function wc_reg_for_menus( $register, $name = '' ) {
|
|||
|
|
if ( $name == 'pa_size' ) $register = true;
|
|||
|
|
return $register;
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Custom attribute slugs are prefixed with `pa_`, so an attribute called `size` would be `pa_size`
|
|||
|
|
|
|||
|
|
Now use your attribute in **Appearance > Menus**. You will notice, however, that it has default blog styling when you click on a link to your taxonomy term.
|
|||
|
|
|
|||
|
|
# Create a template
|
|||
|
|
|
|||
|
|
You need to theme your attribute to make it display products as you want. To do this:
|
|||
|
|
|
|||
|
|
1. Copy `woocommerce/templates/taxonomy-product_cat.php` into your theme folder
|
|||
|
|
2. Rename the template to reflect your attribute – in our example we’d use `taxonomy-pa_size.php`
|
|||
|
|
|
|||
|
|
You should now see this template when viewing taxonomy terms for your custom attribute.
