WPF DockLayoutManager- LayoutGroup dock controls to the left side(when pinning)

Question

I am using DevExpress' DockLayoutManager. Within the DockLayoutManager, I use LayoutGroup, and within LayoutGroup, I have three LayoutPanels stacked vertically.When I unpin the controls I want all of the panels to dock to the left. By default two of them go top and one goes left. Is there a property in XAML that I must set?

 <dxd:DockLayoutManager x:Name="dockLayoutManager"  >

        <dxd:LayoutGroup Orientation="Horizontal" x:Name="LayoutRoot">
            <dxd:LayoutGroup Orientation="Vertical">
                <dxd:LayoutPanel ItemWidth="200"
                             Caption="Statuswort"
                             Padding="1">
                    <TextBox BorderThickness="0" />
                </dxd:LayoutPanel>
                <dxd:LayoutPanel ItemWidth="200"
                             Caption="Steuerwort"
                             Padding="1">
                    <TextBox BorderThickness="0" />
                </dxd:LayoutPanel>
                <dxd:LayoutPanel ItemWidth="200"
                             Caption="Übersicht"
                             Padding="1">
                    <TextBox BorderThickness="0" />
                </dxd:LayoutPanel>
            </dxd:LayoutGroup >

Use the AutoHideGroup.AutoHideType attached property:

<dxd:DockLayoutManager>
    <dxd:LayoutGroup Orientation="Horizontal" x:Name="LayoutRoot">
        <dxd:LayoutGroup Orientation="Vertical">
            <dxd:LayoutPanel ItemWidth="200" dxd:AutoHideGroup.AutoHideType="Left"
                         Caption="Statuswort"
                         Padding="1">
                <TextBox BorderThickness="0" />
            </dxd:LayoutPanel>
            <dxd:LayoutPanel ItemWidth="200" dxd:AutoHideGroup.AutoHideType="Left"
                         Caption="Steuerwort"
                         Padding="1">
                <TextBox BorderThickness="0" />
            </dxd:LayoutPanel>
            <dxd:LayoutPanel ItemWidth="200" dxd:AutoHideGroup.AutoHideType="Left"
                         Caption="Übersicht"
                         Padding="1">
                <TextBox BorderThickness="0" />
            </dxd:LayoutPanel>
        </dxd:LayoutGroup>
    </dxd:LayoutGroup>
</dxd:DockLayoutManager>
