Hi,

Is it possible to hide all empty folders and markupNodes with no control points from a qMRMLSubjectHierarchyTreeView ?

Thank you

You can use the `showEmptyHierarchyItems` property in the proxy model.

> markupNodes with no control points

I’d probably change the default markup node to have a certain attribute, and then when a control point is added, remove that attribute (or change the value). Use it in conjunction with [excludeNodeAttributeNamesFilter](https://github.com/Slicer/Slicer/blob/main/Modules/Loadable/SubjectHierarchy/Widgets/qMRMLSubjectHierarchyTreeView.h#L96)
