Right-clicking a radio button shows the convert to drop-down option in Studio Pro 11: error thrown due to unsupported Dojo-based widget

Issue

In Studio Pro 11, the drop-down widget is officially unsupported due to the migration of pages to React. However, when right-clicking a Radio button, the context menu presents the option to Convert to > Drop-down widget. Proceeding with this conversion throws an error:

Widget drop-down is not supported in React client. Right-click this error to convert it to an alternative widget type

 Studio Pro throws an error because the drop-down widget is Dojo-based and is no longer supported.

Environment

Studio Pro v11.0.0 and newer

Cause

Studio Pro 11 did not update the context menu option to reflect the removal of the Dojo-based drop-down widget. As a result, the outdated conversion option remains visible and, when used, produces an error because the drop-down widget is no longer supported in the React-based page framework. The issue has been added to the backlog to be rectified.

Solution/Workaround

There is currently no direct fix available. The following workaround is recommended:

• Avoid using the Convert to > Drop-down option when right-clicking a Radio button in Studio Pro 11.
• Replace the Radio button with the supported replacement widget by adding it directly from the Toolbox.
