# popupPopover

A popover that presents a web view loaded with the pop-up page for this action, or `nil` if no popup is specified.

```
var popupPopover: NSPopover? { get }
```

## Discussion

This popover contains a view controller with a web view preloaded with the pop-up page. It automatically adjusts its size to fit the web view’s content size. The [`presentsPopup`](/documentation/WebKit/WKWebExtension/Action/presentsPopup) property should be checked to determine the availability of a pop-up before using this property.  Dismissing the popover will close the pop-up and unload the web view.
