To get the button on the right, you're going to have to re-template the expander. Here is the full xaml you'll need:

<TextBlock Text="Vertical2"/>
<TextBlock Text="Vertical3"/>
</StackPanel>
</toolkit:Expander>
</Grid>
This will produce a control that looks like this:
If you can live with the button on the left, then the solution becomes alot easier:
<toolkit:Expander>
<toolkit:Expander.Header>
<StackPanel Orientation="Horizontal">
<TextBlock Text="Horizontal1 "/>
<TextBlock Text="Horizontal2 "/>
</StackPanel>
</toolkit:Expander.Header>
<StackPanel Orientation="Vertical">
<TextBlock Text="Vertical1"/>
<TextBlock Text="Vertical2"/>
<TextBlock Text="Vertical3"/>
</StackPanel>
</toolkit:Expander>
which produces this:
