Hello,  
I Would like to show only ““vtkMRMLMarkupsFiducialNode”” in my SubjectHierarchyTreeView widget.  
I manage to hide the majority of node types thanks to this snipet 🙂

```auto
self.shFiducialTreeView = slicer.qMRMLSubjectHierarchyTreeView()
self.shFiducialTreeView.nodeTypes = ["vtkMRMLMarkupsFiducialNode"]
self.shFiducialTreeView.setShowRootItem(False)
self.shFiducialTreeView.setMRMLScene(slicer.mrmlScene)

```

But as you can some folder Nodes are still showing :

Do you have a solution for this issue ? what am i doing wrong ?

Thanks a lot

Folders are shown by default (even if they are empty), because otherwise you could not create new folders and drag-and-drop nodes into them. In recent Slicer Preview Releases you can control visibility of empty folders.

For that you need to do the following:

```auto
proxyModel = self.shFiducialTreeView.sortFilterProxyModel()
proxyModel.showEmptyHierarchyItems = False

```
