# WKOpenPanelParameters

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

## Declaration

```swift
@MainActor class WKOpenPanelParameters
```

## Overview

Overview Use a 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:) method of its UI delegate object when it displays a file upload control.
