      {
        "id": 3,
        "label": "Cat"
      }
    ]
  }
]

• What is the expected behavior?
  If I don't give an id it should generate it.

[
  {
    "label": "Animal",
    "nodes": [
      {
        "label": "Dog"
      },
      {
        "label": "Cat"
      }
    ]
  }
]

• What is the motivation / use case for changing the behavior?
  Common usage is like this. In addition, it is tiring for the end user to create an id for unidentified data.
