# Order Line Properties

With the use of [Properties](https://docs.umbraco.com/umbraco-commerce/key-concepts/properties), Umbraco Commerce allows a lot of flexibility to capture whatever data you need to record against an Order Line. To complement that functionality, it is also possible to configure those properties to be editable within the backoffice UI.

Order Properties are defined as manifest entries in your [`umbraco-package.manifest`](https://docs.umbraco.com/umbraco-cms/extending/package-manifest).

```json
"extensions": [
    {
        "type": "ucOrderLineProperty",
        "alias": "Uc.OrderLineProperty.FirstName",
        "name": "Customer FirstName",
        "weight": 400,
        "meta": {
            "propertyAlias": "firstName",
            "readOnly": false,
            "showInOrderLineSummary": true,
            "summaryStyle": "inline",
            "editorUiAlias": "Umb.PropertyEditorUi.TextBox",
            "labelUiAlias": "Umb.PropertyEditorUi.Label"
        }
    }
]
```

Each entry must have a type of `ucOrderLineProperty` along with a unique `alias` and `name`. An optional `forEntityTypes` key can also be defined to control whether the property is visible on the Cart editor, or the Order editor, or both. The `forEntityTypes` is an array and can accept either or both of `uc:cart` or `uc:order` values.

A `meta` entry provides configuration options for the property

## Localization

When displaying your properties in the backoffice UI it is necessary to provide localizable labels. This is controlled by Umbraco's [UI Localization](https://docs.umbraco.com/umbraco-cms/extending/language-files/ui-localization) feature.

Umbraco Commerce will automatically look for the following entries:

| Key                               | Description                    |
| --------------------------------- | ------------------------------ |
| `ucProperties_{alias}Label`       | A main label for the property  |
| `ucProperties_{alias}Description` | A description for the property |

Here `{alias}` is the property alias of a property.
