TabOverflowBehavior: On TabbedMdiHost, how can I have tabs overflow to a new line?

I want to be able to keep all of the tabs visible instead of hiding in a scroll, in a menu, or shrinking.

Is there a setting or way to allow the overflowing tabs just to create a new row (wrap the line)? 

            <docking:DockSite>
                <docking:Workspace>
                    <docking:TabbedMdiHost TabOverflowBehavior="{Binding TabOverflowBehavior}"/>
                </docking:Workspace>
            </docking:DockSite>

Hello,

While we don't have a direct option for that, I believe you can use code like this to use a WrapPanel for the items panel:

<docking:TabbedMdiHost x:Name="tabbedMdiHost">
	<docking:TabbedMdiHost.TabControlStyle>
		<Style TargetType="docking:TabbedMdiContainerTabControl">
			<Setter Property="ItemsPanel">
				<Setter.Value>
					<ItemsPanelTemplate>
						<WrapPanel />
					</ItemsPanelTemplate>
				</Setter.Value>
			</Setter>
		</Style>
	</docking:TabbedMdiHost.TabControlStyle>
</docking:TabbedMdiHost>

Hello, Thank you for sharing the XAML, it looks great but one major flaw. The drag-and-drop doesn't work. Do you have any suggestions about how we could implement it so that we could still reorder the tabs and move to other tab groups?

Correct, unfortunately drag and drop reorder won't work without the AdvancedTabPanel primitive control being used in the ItemsPanelTemplate.  AdvancedTabPanel doesn't support a wrapping layout option at this time.  I have logged it as a suggestion for possible future implementation.
