Commented Feature: Expandable Property not expanded by default [20054]

Based on discussion https://wpftoolkit.codeplex.com/discussions/452722, user wants to have an expand property expanded by default.

Maybe having a new ExpandableObjectAttribute which take a true/false parameter would do the job.

I read on the Community edition section of the following page:

[http://wpftoolkit.codeplex.com/wikipage?title=Improvements230](http://wpftoolkit.codeplex.com/wikipage?title=Improvements230)

In PropertyGrid, you can now set the ExpandableObjectAttribute parameter. A value of true will set PropertyItem to Expanded, while false will set PropertyItem to Collapsed.

I guess this should not be in the Community edition section but in the Plus edition section?
