Outlook will have collapsible left panel. If the panel is collapsed content will be displayed in the floating panel.I tried creating this in WPF with XAML without C#. I Created the Style but with hardcoding in two place.

This Expander style has tow template Default expander Template and one for Floating the Content. Here I used Popup control to get floating panel. And also I added two styles for Togglebutton used in expander, One for Horizontal Button Style and another for vertical Button Style

     <controltemplate x:Key="RightExpander" TargetType="{x:Type Expander}">
            <border SnapsToDevicePixels="true" Background="{TemplateBinding Background}"
                                BorderBrush="{TemplateBinding BorderBrush}"
                    </grid><grid .RowDefinitions>
                        <rowdefinition Height="Auto"/>
                        <rowdefinition Height="Auto"/>

                    <togglebutton Width="{TemplateBinding ActualWidth}"   Margin="0,1,0,1" MinHeight="0" MinWidth="30" x:Name="HeaderSite"
                                              Style="{StaticResource LeftPanelCollpasedButtonStyle}" Content="{TemplateBinding Header}"
                                              ContentTemplate="{TemplateBinding HeaderTemplate}"
                                              ContentTemplateSelector="{TemplateBinding HeaderTemplateSelector}"
                                              FontFamily="{TemplateBinding FontFamily}" FontSize="{TemplateBinding FontSize}"
                                              FontStretch="{TemplateBinding FontStretch}" FontStyle="{TemplateBinding FontStyle}"
                                              FontWeight="{TemplateBinding FontWeight}" Foreground="{TemplateBinding Foreground}"
                                              HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}"
                                              Padding="{TemplateBinding Padding}"
                                              VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}"
                                              IsChecked="{Binding Path=IsExpanded, Mode=TwoWay, RelativeSource={RelativeSource TemplatedParent}}" DockPanel.Dock="Top"/>

                    <popup x:Name="popup" AllowsTransparency="True"  IsOpen="False" Placement="Bottom" PlacementTarget="{Binding ElementName=HeaderSite}">

                            <contentcontrol x:Name="shadow" Visibility="Collapsed" HorizontalAlignment="Stretch" Style="{DynamicResource ShadowTemplate}"
						VerticalAlignment="Stretch" Content="ContentControl"  Opacity="1"
						Margin="2,0,2,0" Foreground="#FF000000"/>
                            <contentpresenter Opacity="1" MinWidth="220"  HorizontalAlignment="Left" Margin="0,0,0,0" x:Name="ExpandSite" Focusable="false" Visibility="Collapsed" VerticalAlignment="Top" />


            </controltemplate><controltemplate .Triggers>

                <trigger Property="IsExpanded" Value="true">
                    <setter TargetName="shadow" Property="Visibility" Value="Visible"/>

                    <setter TargetName="ExpandSite" Property="Margin" Value="5,5,5,5"/>

                    <setter Property="Visibility" TargetName="ExpandSite" Value="Visible"/>

                <trigger Property="IsEnabled" Value="false">
                    <setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}"/>
