Partition layout : traversing 2 kinds of children

[b-barry]

Hello,

At first, I would like to thank you for your great work on this library. It helped me a lot of for all my data visualization usecase.

However, I got a special kind of hierarchical data that I wondering if it is possible to solve it with d3-hierarchy ( partition).

In JSON, I have to 2 fields that can be used as "children", "childs" and "details".

[
  {
    "name": "Element name 1",
    "value": 218110166.51914096,
    "percent": 0.34384346972710306,
    "childs": [
      {
        "name": "Element name 2",
        "value": 218110166.51914096,
        "percent": 100.0,
        "childs": null,
        "details": null
      }
    ],
    "details": [
      {
        "name": "Element name 40",
        "value": 131343750.0,
        "percent": 60.218994875909885,
        "childs": null,
        "details": null
      },
      {
        "name": "Element name 41",
        "value": 59933784.924403764,
        "percent": 27.478675515634013,
        "childs": null,
        "details": null
      }
    ]
  }
]

Based on some conditions, I have to navigate through "childs" or "details".
I use the partition layout to traverse the tree either by "childs" or "details" by implementing the partition.children callback function.
This works well by I stay with one side of the tree untouched after the traversing.
For my usecase, at the beginning, I need to navigate through the two fields by keeping all the state of the previous navigation. So traversing through all "childs" like it was "children", the same thing for "details"
I didn't find any function in API that can help to achieve this kind of behavior.
Do it possible to perform this double navigation with the partition layout ?

Thanks for your help
