[tree view] Support for enabling checkboxes only for leaf nodes

[Skykingeagle]

Reference: #12883

While the parent / children selection relationship works with the checkBoxSelectionProp

Would there be any way to restrict the checkboxes for only leaf nodes?

Hey @Skykingeagle ... I'll add this to the board for the team to have a look!
I guess this could be possible, but I'd like the teams opinion on that first.

You can achieve this a custom TreeItem component, here is a basic implementation

Let me know if this solves your problem

@flaviendelangle thanks for the example! We're using it like that too, but really dislike the any escape hatch usage in slotProps={{ checkbox: { visible: !status.expandable } as any }}. Is there a chance to get this properly typed and maybe supported a bit more elegantly out of the box?

In case it helps with prioritisation: we're a paying customer, our latest order number is 💳 #84512.

Hey @TheRealCuran ... could you open up a new ticket for that? We try to separate and track individually to better plan and implement in small batches! Thank you! 👍🏼

@michelengelen see #15674 for the new ticket. Though I think we could have done this here? Less cluttering can be very helpful too, for finding issues again.

The problem with re-using old issues is that we tend to diverge from the original topic and end up with an issue that is very hard to understand.

If the reason the keep discussing is not that the fix does not work at all, we tend to prefer opening new issues 👍
