# Type Alias: ContentItem

```ts
type ContentItem = 
  | PdfPage
  | AnnotationBase
  | FormXObject;
```

Represents a document object that can be referenced as a content item from the structure tree
(the target of an `OBJR` link). It can be a [PdfPage](../classes/PdfPage), an [AnnotationBase](../classes/AnnotationBase), or a
[FormXObject](../classes/FormXObject).
(An image XObject can also be a target in PDF, but it is not yet wrapped.)
