# allowsMultipleSelection

Returns a Boolean value indicating whether users can select multiple thumbnails in the thumbnail view at one time.

```
var allowsMultipleSelection: Bool { get set }
```

## Return Value

<doc://com.apple.documentation/documentation/Swift/true> if users can select multiple thumbnails simultaneously, <doc://com.apple.documentation/documentation/Swift/false> otherwise.

## Discussion

By default, `PDFThumbnailView` allows only a single thumbnail to be selected at one time. When this is the case, you can get the PDF page that corresponds to the selected thumbnail using the `PDFView` method [`currentPage`](/documentation/PDFKit/PDFView/currentPage).

When multiple selections are enabled, however, you must use [`selectedPages`](/documentation/PDFKit/PDFThumbnailView/selectedPages) to get the pages that correspond to the set of selected thumbnails.
