Default ControlTemplate for Expander

expander

can someone (probably using Blend) provide me a working default ControlTemplate for the WPF Expander? I want to do some slight modification but seems that I cannot find a source for a valid template.

Thanks in advance.

What is Expander in WPF?

The WPF Expander represents a control with an expanded view where the contents of the expanded area can be expanded or collapsed. There are two ways to create an expander control in a WPF app. We can create an Expander control at design-time using the <Expander> element of XAML.

I have blend, and can help you out. Here is what Blend generated for me.
