# Cutline

> Feature introduced in Story 3.2.0

The first required metafield is **`theme.cutline`** 

```
theme.cutline
```

The content type is: Text, Single line text. 

This metafield is used for both the swatch label and subtitle for the product which helps with identifying the color version of the current product:

![](/files/gVktxX1mM8BlIBBMfQRH)

Start by defining a **Products** metafield and name it **Cutline**. Then change the Namespace from `my_fields` to `theme`:

{% hint style="info" %}
Important step: Rename **`my_fields`** to **`theme`**
{% endhint %}

![](/files/gfdIDrwzlM7gPcMqpozV)

Next, add a description. You can use Cutline again. Then click on **Select content type** and choose **Text**, **Single line** as the type:

![](/files/77UoYzCiUBKMQ3asfIkB)

**Save** the definition. 

### Check the saved metafield

Your final metafield should look like this:

![](/files/z4MDQwdJEpClSyzSlgNr)

{% hint style="success" %}
Please ensure you change the Namespace and key to this custom version for Story:\
\
\&#xNAN;**`theme.cutline`**\
\
By default, the namespace begins with **`my_fields`**. This will need to be changed to **`theme`**
{% endhint %}

The content type is **Text** and style is **Single line text**. 

### Next step

We require a second metafield to be defined:

{% content-ref url="/pages/ujg62BwEKsyoKNaLtA7Z" %}
[Siblings collection](/siblings/product-siblings/siblings-collection.md)
{% endcontent-ref %}
