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:

$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:

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.
