Thank you for contacting us.
If you are looking for automatic conversion from a Ribbon interface to the menu/toolbar interface, Telerik WinForms controls do not support such. To be honest, I am not familiar with any other vendor that supports that in the .NET world out-of-the-box. The only suggest I can make is to have two forms with the respective interface, and show the one that the user selects. Note that in order to have proper Ribbon experience, the RibbonBar has to overlap the form's titlebar. This is why we offer a dedicated RibbonForm. You can nevertheless use our RibbonBar as a standalone control on a regular form or Telerik RadForm.
This seems to be a good feature to have, so we will appreciate your feedback on why would you need such a rollback. We will also appreciate it if you share your experiences with the other vendor's tools, so that we know how to make this functionality better in case we decide to do this.
