# certificatePanelShowHelp(_:)

Implements custom help behavior for the modal panel.

```
func certificatePanelShowHelp(_ sender: SFCertificatePanel!) -> Bool
```

## Parameters

`sender`

The certificate panel for which to implement custom help.

## Discussion

You can use this delegate method to implement custom help if you call the <doc://com.apple.documentation/documentation/SecurityInterface/SFCertificatePanel/setShowsHelp(_:)> method to display a help button in the sheet or panel. If you are not implementing custom help, do not implement this method.
