Hello,

I inspected the Data module and found out that it is using qMRMLSubjectHierarchyTreeView widget for showing the nodes in a tree view. I wanted to customize the Data module by creating my own custom widget. So I created a widget, with a combo box that selects from the list plans. The plans contains lines. I want to show the lines like a list and with all the added functionality of hide/show `eye` button, transformation tracking, color picking, and their IDs like how the Data module shows it. So I created one instance of qMRMLSubjectHierarchyTreeView, and set it like this.

```python
self.lineDetailView = qMRMLSubjectHierarchyTreeView()
self.lineDetailView.setMRMLScene(slicer.mrmlScene)

```

The problem is that it shows all the nodes and folders. I just want to show the line that corresponds to the selected plan. I thought I could do the following

```python
self.lineDetailView.nodeTypes = ['vtkMRMLMarkupsLineNode']

```

but this shows the folders with the lines. even if it didn’t show the folders, I don’t know how to delete the other line nodes that doesn’t belong to the current selected plan.

Is there a way to hide any node, be it a folder node or a segmentation node or a line node using its ID from the tree view? I just to want to hide from the tree view. not from the scene.

Any help will be appreciated. Thank you for replying to me.

Have you looked at the available filtering options as I suggested in the other thread?

All it takes is a bit of creativity. For example you can set the plan name or some other ID as an attribute to the lines, and you can filter by attribute when you select a plan.

Yes, I did exactly what you told here. I attached the plan name itself as an attribute to the line and then I filtered it whenever the combo box text changes. These lines have segmentation nodes attached to it. I now have to show the segmentation nodes below the appropriate line like a tree view. Are there any functions for that?

Thank you very much for your help btw.

I’d probably organize all nodes that belong to a plan in folders, and filter the folders.

But I feel like I know too little about the use case to give you a comprehensive answer.
