6.2 Dynamic Query Lists

To use Dynamic Query Lists with Headless Server, Headless Server Search needs to be set up (see Section 6.1.1, “Content Query Form” in Blueprint Developer Manual for details about Dynamic Query List content).

Dynamic Query Lists are handled with the queryListAdapter. The following functionality is supported:

  • Paging
  • Limiting the result size
  • Filter by predefined fields
  • Sort by predefined fields

The following GraphQL query is a simple example for fetching data from a CMQueryList content.

{
  content {
    queryList(id: "7692") {
      title
      items {
         ... on CMLinkable {
           title
         }
      }
    }
  }
}
  

The following parameter can be passed to the QueryListAdapter to customize the Dynamic Query List result:

  • offset: The offset for paging. Available as pagedItems in graphql schema.

The following GraphQL query is a simple example for fetching paged data from a CMQueryList content.

{
  content {
    queryList(id: "7692") {
      title
      pagedItems(offset: 3) {
        title
      }
    }
  }
}
