+# Popup Annotation  
+
+A **Popup annotation** displays a pop-up window containing text associated with a parent annotation, such as a [Text]({%slug radpdfprocessing-model-annotations-text%}), [Line]({%slug radpdfprocessing-model-annotations-line%}), [TextMarkup]({%slug radpdfprocessing-model-annotations-text-markup%}) or [Stamp]({%slug radpdfprocessing-model-annotations-stamp%}) annotation. When closed, a popup annotation is invisible. When open, it should appear as a pop-up window at a specified location on the page.
+
+The **PopupAnnotation** class is a derivative of the **Annotation** class and it exposes the following properties:
+
+|Property|Description|
+|---|---|
+|**ParentAnnotation**|Gets or sets the parent [MarkupAnnotation]({%slug radpdfprocessing-model-annotations-overview%}) that this popup is associated with.|
+|**IsOpen**|Gets or sets a value indicating whether the popup is initially open.|
+
+## Creating a PopupAnnotation
+
+Popup annotations are typically created in association with another markup annotation, such as Text, Line, TextMarkup or Stamp. The following example shows how to create a PopupAnnotation  associated with a TextAnnotation:
+
+<snippet id='libraries-pdf-model-annotations-popup-create'/>
+
+The popup annotation will display the contents of the text annotation in a pop-up window.
+
+## Creating a PopupAnnotation with FixedContentEditor
+
+When creating a TextAnnotation with the [FixedContentEditor]({%slug radpdfprocessing-editing-fixedcontenteditor%})'s **DrawTextAnnotation** method, you can also associate a popup annotation by setting the `addPopup` parameter to **true**:
+
+<snippet id='libraries-pdf-model-annotations-popup-create-with-fixedcontenteditor'/>
+
+This code creates a [TextAnnotation]({%slug radpdfprocessing-model-annotations-text%}) with an associated **PopupAnnotation**. The popup will display the text provided in the method call.
