Hi Juraj,
Thank you for contacting Syncfusion Support.
With
current implementation of Ribbon control there is no direct support to show the
Ribbon without RibbonTab header.
We have created workaround sample to
achieve your requirement. In this sample we have overridden the Ribbon style for
Office2016White theme to achieve your requirement. In this sample we have set
"ribbonTabBorder" Visibility as Collapsed and adjusted the
“PART_RibbonWindowPanel" height.
Please download the sample from the
below location.
Sample:WpfApp2
Regards,
Priyanga B
