# Link

A navigation link including its URL, title, type, and related child links.

## Type Definition

```graphql
type Link {
  levels: Int
  links: [Link]
  title: String
  type: String
  url: String
  target: String
  product: Product
  productGroup: ProductGroup
  page: Page

```

## Fields

| Field | Type | Description |
|-------|------|-------------|
| levels | Int | The maximum depth of nested child links below this link. |
| links | [Link] | The list of child links for this link. Each child link can itself have further children, forming a hierarchy. |
| title | String | The display name of the link, typically shown as the link's label in navigation components. |
| type | String | The type of object this link points to, such as 'product', 'category', 'page', or 'article'. |
| url | String | The URL that this link points to. This can be an internal or external address. |
| target | String | The target attribute for the link, indicating how the link should be opened (e.g., in a new tab). |
| product | Product | The product object associated with this link, if the link points to a product. |
| productGroup | ProductGroup | The category object associated with this link, if the link points to a category. |
| page | Page | The page object associated with this link, if the link points to a page. |
| article | Article | The article object associated with this link, if the link points to an article. |

## Relationships

The Link type represents a hierarchical navigation structure. It can point to various content types in the system through its optional relationship fields: Product, ProductGroup, Page, and Article. Links can contain child links through the `links` field, allowing for nested navigation hierarchies with configurable depth through the `levels` field.

## Example

```graphql
{
  title
  url
  type
  target
  levels
  links {
    title
    url
    type
  }
  product {
    id
    name
  }
  productGroup {
    id
    name
  }
}
```
