Backstage

The Backstage is the menu that’s hidden behind the File button in the top-left corner in office. Let’s fill the backstage with items:

<!--Backstage-->
<Fluent:Ribbon.Menu>
    <Fluent:Backstage>
        <Fluent:BackstageTabControl>
            <Fluent:BackstageTabItem Header="New" />
            <Fluent:BackstageTabItem Header="Print" />
            <Fluent:Button Header="Blue" />
        </Fluent:BackstageTabControl>
    </Fluent:Backstage>
</Fluent:Ribbon.Menu>
