I can't drag nodes into a folder in the subject hierarchy

I’m sure this is a silly question, but I can’t click-and-drag nodes in the subject hierarchy to put them into a folder. I’m using a Macbook with a normal touchpad, no external mouse or anything. Every time I click and drag a file it just highlights everything the mouse goes over, as though I were holding down the shift key to select multiple files.

See the attached video. All I’m trying to do is click-and-drag a single node into the folder in the subject hierarchy.

There doesn’t seem to be a cut/paste option either, so I have no idea how to move the nodes. Does anyone know how to do this?


Hmm, don’t know. Dragging nodes into folders in the subject hierarchy works for me on a mac trackpad (mac book air M2)

Can you paste this in the Python console:

dmw = slicer.modules.data.widgetRepresentation()
shtvs = findChildren(dmw, className='qMRMLSubjectHierarchyTreeView')
shtv = shtvs[0]

If it gives False, try shtv.dragEnabled = True and see what happens.
