How do I set a spacer for this list, where do I have groups? There is a spacer option for finder treeList, but I didn’t find anything here. Please advise.
I’m not clear on how you think it’s supposed to know what should have this added to it and what shouldn’t. You’re explicitly calling list, which does only a single level of the data. treeList does more, because that’s what treeList's purpose is.
