How can I add Vertical separator to WPF Ribbon, to RibbonGroup? I have tried something like that, but i got horizontal separator istead of vertical.
<r:RibbonGroup>
<r:RibbonButton Command="{StaticResource SomeButton}" />
<r:RibbonSeparator></r:RibbonSeparator>
<r:RibbonToggleButton IsChecked="False" Command="{StaticResource AnotherButton}"/></r:RibbonToggleButton>
</r:RibbonGroup>
So how can I make vertical separator?
