Add multiple parent ids

[philipstanislaus]

Not sure I follow – can you give an example of how the function call and how inputs/outputs would look?

Thanks!

const tree = arrayToTree([
    { id: '4', parentId: null, custom: 'abc' },
    { id: '1941', parentId: ['4', '418'], custom: 'de' },
    { id: '1', parentId: ['418'], custom: 'ZZZz' },
    { id: '418', parentId: null, custom: 'ü'},
])

result:

[
    { data: { id: '4', parentId: null, custom: 'abc' }, children: [
        { data: { id: '1941', parentId: '4', custom: 'de' }, children: [] },
    ] },
    { data: { id: '418', parentId: null, custom: 'ü'}, children: [
        { data: { id: '1941', parentId: '418', custom: 'de' }, children: [] },
        { data: { id: '1', parentId: '418', custom: 'ZZZz' }, children: [] },
    ] },
]

Thanks for the example.

Can you give a bit context which use cases that would cover?

It seems to me like a very special use case that would complicate performant-array-to-tree quite a bit.

It is a special use case, just thought it would be a nice addition to extend the package usage.

Can you give a bit context which use cases that would cover?

A structure where a child can be nested in multiple parent, you can imagine it applied to a nested menu for instance.

Feel free to close the issue if you don't think it's relevant.

This issue must have slipped through the cracks – sorry for that. I am not sure that this feature will be widely used, and feel the negative performance impact a potential implementation could have does not make adding this a good trade-off.

If more users are looking for that feature, I'm happy to re-open this issue.
