# Add Custom Taxonomies To Product Variations

**Coming soon:** Iconic Show Single Variations is becoming part of Kadence Shop Kit. You may see both names used while we update the product, documentation, and customer experience.

By default, product variations will inherit the categories ( `product_cat` ) and tags ( `product_tag` ) from the parent product.

But what if you’ve added your own taxonomies to the parent product? For example, maybe you‘re using a **Brands** plugin and want your variations to show up when you filter by brand.

Well in v1.1.10 of Show Single Variations it became possible to add your own taxonomies to be ported over to the variations on product save.

Let’s take a look at how to add the `product_brand` taxonomy to the taxonomies list. In the below example, if I filter by the brand of “Nike” there’s a single result; our parent variable product. Let’s change that.

![example of product brand on display](https://docs.nexcess.com/wp-content/uploads/2026/06/example-of-product-brand-on-display.png)Firstly, add the following code to your child theme’s `functions.php` file:

```
/**
 * Add product_brand to taxonomies list for variations.
 * 
 * @param array $taxonomies
 *
 * @return array
 */
function iconic_add_brands_to_variations( $taxonomies ) {
	$taxonomies[] = 'product_brand';

	return $taxonomies;
}

add_filter( 'iconic_wssv_variation_taxonomies', 'iconic_add_brands_to_variations', 10, 1 );
```

We’re filtering the `$taxonomies` array for variations and adding `product_brand` to the list.

With this snippet enabled, when you re-save the parent product, any brands associated with the product will also be saved to the variations.
