Add <LineItems> component

[marcomontalbano]

What I did

I created a new <LineItems> component. This component is able to render an array of line_items, parcel_line_items, and stock_line_items and we could add more in the future (e.g. return_line_items).

There's an editable prop that works only for line_items. When true you can update the lineItem quantity or remove the lineItem.

<LineItems items={[]} editable />

Order.LineItems.mov

Relevant changes

• <OrderSummary> has been updated and now it uses the LineItems component.
• <ShipmentParcels> has been updated and now it uses the LineItems component.

Next Steps

• There're other components in our app-* that implement a custom LineItem, we should remove them and start using <LineItems> instead.

Checklist

• Make sure your changes are tested (stories and/or unit, integration, or end-to-end tests).
• Make sure to add/update documentation regarding your changes.
• You are NOT deprecating/removing a feature.

👍 It looks like a very good component that is going to simplify the applications that will require line items component!
