# Order summary component

The order summary component lists the products in the customer's cart at checkout-time and provides an item-level and order-level breakdown of how much they are to be charged, denominated in the [checkout-session's](https://docs.digitalriver.com/digital-river-api-reference/2021-12-13/drop-in-checkout-sessions/checkout-sessions-basics) [`currency`](https://docs.digitalriver.com/digital-river-api-reference/2021-12-13/drop-in-checkout-sessions/checkout-sessions-basics#currency).

For each of that resource's [`items[]`](https://docs.digitalriver.com/digital-river-api-reference/2021-12-13/drop-in-checkout-sessions/checkout-sessions-basics#product-data), the component displays its `quantity` along with the `image` and `name` that you either passed in [`productDetails`](/digital-river-api/product-management/skus.md#product-details) or stored in the referenced [SKU](/digital-river-api/product-management/skus.md#skus).

As customers progress through the various checkout stages, Digital River computes applicable taxes and shipping costs and then updates the experience.

## Creating the order summary component

To create an instance of the order summary component, pass `'ordersummary'` to [`createComponent()`](/digital-river-api/developer-resources/digitalrivercheckout.js-reference/digitalrivercheckout-object/components.md#createcomponent-componenttype).

```javascript
let orderSummaryComponent;
...
orderSummaryComponent = components.createComponent('ordersummary');
```

## Mounting the order summary component

To attach the order summary component to your DOM, pass the `id` of its container to [`mount()`](/digital-river-api/developer-resources/digitalrivercheckout.js-reference/digitalrivercheckout-object/components.md#mount-elementid).

```javascript
<div id="order-summary-container" style="display: block">
...
orderSummaryComponent.mount('order-summary-container');
```
