# ProductGroupConnection

A connection to a list of ProductGroup items.

## Connection Structure

```graphql
type ProductGroupConnection {
  edges: [ProductGroupEdge]
  nodes: [ProductGroup]
  pageInfo: PageInfo!
  totalCount: Int
}
```

## Pagination Arguments

| Argument | Type | Description |
|----------|------|-------------|
| first | Int | Returns the first n items from the list |
| last | Int | Returns the last n items from the list |
| before | String | Returns items before the specified cursor |
| after | String | Returns items after the specified cursor |

## PageInfo Structure

The `pageInfo` object contains pagination metadata about the connection. It provides information about whether additional pages exist and supplies cursor values for navigating between pages. The `pageInfo` field is required and always returns a `PageInfo` object with fields including `hasNextPage`, `hasPreviousPage`, `startCursor`, and `endCursor`.

## Example

```graphql
query {
  productGroups(first: 10, after: "eyJpZCI6IDEwMH0=") {
    edges {
      cursor
      node {
        id
        name
      }
    }
    nodes {
      id
      name
    }
    pageInfo {
      hasNextPage
      hasPreviousPage
      startCursor
      endCursor
    }
    totalCount
  }
}
```

## Edge Type

The `ProductGroupEdge` type represents an individual item in the connection. Each edge contains a `node` field that holds the actual `ProductGroup` object, and a `cursor` field that provides an opaque string for pagination purposes. The cursor can be used in subsequent queries with the `before` or `after` arguments to navigate through the list.
