Как использовать gridsplitter на динамическом макете?

Для жизни я не могу заставить элемент управления gridsplitter вести себя так, как я хочу.

В приведенном ниже макете мне нужен gridspliter справа от каждого списка, который будет расширяться илисверните это представление списка и измените размер других представлений списка соответствующим образом.

Расширители и их (зеленые) панели не должны изменять размер.

Пожалуйста, помогите!Этот элемент управления сводит меня с ума.

Это не идеально, но вот решение, к которому я иду: 

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*" MinWidth="100" />
        <ColumnDefinition Width="Auto" />

        <ColumnDefinition Width="*" MinWidth="100" />
        <ColumnDefinition Width="Auto" />

        <ColumnDefinition Width="*" MinWidth="100" />
        <ColumnDefinition Width="Auto" />
    </Grid.ColumnDefinitions>
    <Border Grid.Column="0" Background="Green">
    </Border>
    <Expander Name="ex1" Grid.Column="1" ExpandDirection="Left" Expanded="ex_Expanded">
        <Border Background="Blue" MinWidth="200" MaxWidth="200">
        </Border>
    </Expander>
    <GridSplitter Grid.Column="1" Width="5" HorizontalAlignment="Left" ResizeBehavior="PreviousAndNext" VerticalAlignment="Stretch" Background="Red" />
    <GridSplitter Grid.Column="1" Width="5" HorizontalAlignment="Right" ResizeBehavior="PreviousAndNext" VerticalAlignment="Stretch" Background="Red" />
    <Border Grid.Column="2" Background="Green">
    </Border>
    <Expander Name="ex2" Grid.Column="3" ExpandDirection="Left" Expanded="ex_Expanded">
        <Border Background="Blue" MinWidth="200" MaxWidth="200">
        </Border>
    </Expander>
    <GridSplitter Grid.Column="3" Width="5" HorizontalAlignment="Left" ResizeBehavior="PreviousAndNext" VerticalAlignment="Stretch" Background="Red" />
    <GridSplitter Grid.Column="3" Width="5" HorizontalAlignment="Right" ResizeBehavior="PreviousAndNext" VerticalAlignment="Stretch" Background="Red" />
    <Border Grid.Column="4" Background="Green">
    </Border>
    <Expander Name="ex3" Grid.Column="5" ExpandDirection="Left" Expanded="ex_Expanded">
        <Border Background="Blue" MinWidth="200" MaxWidth="200">
        </Border>
    </Expander>
</Grid>
