<div data-8select-widget-id="8.SET" data-sku="insert-sku-of-currently-added-product" data-touchpoint="cart-layer"></div>
```

{% endcode %}

## Show similar items via 8.SIMILAR

{% code overflow="wrap" %}

```html
<div data-8select-widget-id="8.SIMILAR" data-sku="insert-sku-of-added-viewed-product" data-touchpoint="cart-layer"></div>
```

{% endcode %}

2. call `_8select.initCSE()` to let the SDK discover the new widget
