[data grid] Same column in different column groups about mui-x HOT 8 CLOSED

Hey @MiraHariri ... what component are you referring to? TreeView?

And could you please provide a minimal live example? That would help us a lot in understanding your problem! Thanks! 🙇🏼

from mui-x.

@michelengelen I'm referring to columnGroupingModel

<DataGridPremium
  apiRef={apiRef}
  rows={[
    {
      id: "1",
      cost_2022: "20",
      variation_2022_2023: "10",
      cost_2023: "30",
      variation_2023_2024: "20",
      cost_2024: "50",
    },
    {
      id: "2",
      cost_2022: "10",
      variation_2022_2023: "20",
      cost_2023: "30",
      variation_2023_2024: "10",
      cost_2024: "40",
    },
  ]}
  columns={[
    {
      headerName: "ID",
      field: "id",
    },
    {
      headerName: "Cost 2022",
      field: "cost_2022",
    },
    {
      headerName: "Variation 2022 2023",
      field: "variation_2022_2023",
    },
    {
      headerName: "Cost 2023",
      field: "cost_2023",
    },
    {
      headerName: "Variation 2023 2024",
      field: "variation_2023_2024",
    },
    {
      headerName: "Cost 2024",
      field: "cost_2024",
    },
  ]}
  columnGroupingModel={[
    {
      groupId: "2022_2023",
      headerName: "2022 - 2023 Variation",
      children: [
        { field: "cost_2022" },
        { field: "variation_2022_2023" },
        { field: "cost_2023" },
      ],
    },
    {
      groupId: "2023_2024",
      headerName: "2023 - 2024 Variation",
      children: [
        { field: "cost_2023" },
        { field: "variation_2023_2024" },
        { field: "cost_2024" },
      ],
    },
  ]}
/>;

I have the field `cost_2023' is duplicated in the 2 groups

This returned an error that a field can't be in multiple groups

Is there a way to achieve this? or a workaround?

from mui-x.

Hi @MiraHariri ... as the docs state:

:warning: a column can only be associated with one group

So, this is not possible and I am not aware of any workarounds for this. The only thing that you could do is probably duplicate that column, but from the structure of your data I would guess this can get out of hand if you scale this up, right?

from mui-x.

Okay, yes I had this option to duplicate data with different column names in mind, and it is doable. But thought if there is a way from the table would be better

Thank you @michelengelen

Hi @MiraHariri ... well, we can definitely improve on this. On the other hand a built-in solution should be preferred. I will try to improve the workaround, but also add this to the board for the team to build a more profound solution. 💪🏼

Sry, this is the wrong issue ... the original issue was #12222 ... closing this again
