# Product detail event

* Selecting variant from variant picker of Smind

This event is fired whenever a user has changed the variant in a product selector, either in a product page, featured product section or quick view and quick add section

<table data-header-hidden><thead><tr><th>Event</th><th>Detail</th></tr></thead><tbody><tr><td><code>variant:change</code></td><td><pre><code>detail: {variant}
</code></pre></td></tr></tbody></table>

\
variant: Is an object variant of Shopify (<https://shopify.dev/docs/api/liquid/objects/variant>)

The "change variant" event will be listened to by other components to update related elements such as product price, inventory status, SKU, add to cart button, and checkout.

Example usage:

```
document.addEventListener('variant:change', ({ detail: event }) => {
    try{
        const variant = event.variant;
        const variantId = event.variant?.id;
        console.log(variant);
        console.log(variantId);
    } catch (error) {
        console.log('error: ', error)
    }
});
```

* Changing the product variant without using Smind’s variant picker.

If you're replacing the variant selection using Smind’s variant picker with a third-party solution, please make sure to dispatch an event after selecting a variant so that other components can listen for the variant change.

The variant change event must be named **"variant:change"** and must include a **variant object** with the same structure as Shopify's default variant object. (<https://shopify.dev/docs/api/liquid/objects/variant>)

Example usage:

```
container.dispatchEvent(new CustomEvent("variant:change", {
    detail: {
      variant
    },
    bubbles: true
  }));
```

<table><thead><tr><th></th><th></th></tr></thead><tbody><tr><td><pre><code>container
</code></pre></td><td>The section container that includes the variant picker</td></tr><tr><td><pre><code>variant
</code></pre></td><td>Object variant that selected</td></tr></tbody></table>
