### Expanded As [Boolean](https://documentation.xojo.com/api/data_types/boolean.html)

Set or return the state of the StackView.

### UseAnimation As [Boolean](https://documentation.xojo.com/api/data_types/boolean.html)

Animate all Views while collapsing/expanding.

### Views() As [ViewController](/add-ons/stackview/version-3/details/viewcontroller.md)

Collection of ViewControllers.

  Views.Add(MyFontView1)
  Views.Add(MyAlignmentView1)
  Views.Add(MyMarginView1)
End If
