# WKOpenPanelParameters

The configuration details of a file upload control in your web content.

```
@MainActor class WKOpenPanelParameters
```

## Overview

Use a [`WKOpenPanelParameters`](/documentation/WebKit/WKOpenPanelParameters) to determine the configuration of a file upload control. You don’t create this object directly. Instead, a web view creates one and passes it to the [`webView(_:runOpenPanelWith:initiatedByFrame:completionHandler:)`](/documentation/WebKit/WKUIDelegate/webView(_:runOpenPanelWith:initiatedByFrame:completionHandler:)) method of its UI delegate object when it displays a file upload control.

## Topics

### Configuring the panel parameters

[`allowsMultipleSelection`](/documentation/WebKit/WKOpenPanelParameters/allowsMultipleSelection)

A Boolean value that indicates whether the file upload control supports multiple files.

[`allowsDirectories`](/documentation/WebKit/WKOpenPanelParameters/allowsDirectories)

A Boolean value that indicates whether the file upload control supports the selection of directories.
