[Question]Ask for help，how to edit the tree data?

[KaLe-Baijiu]

Question

I used a recursive method to present my nested data structure.

But now I need to add, delete and modify it. I don't know how to apply the modified data to the original data.

I think I really need an editable tree control. I don't have the ability to reinvent the wheel.

I hope you can give me a little help. Thank you very much!

Code sample

def build_filter_content(
            self,
            data: Union[
                "FilterContent",
                "FileFilterContent",
                "TrackTraceFilterContent",
                "WorkSheetFilterContent",
            ],
            level: int = 0,
    ):
        if type(data) in (
                FileFilterContent,
                TrackTraceFilterContent,
                WorkSheetFilterContent,
        ):
            return self.build_sub_filter_content(data, level=level)
        col_container = ft.Container(
            margin=ft.margin.only(left=level * 30),
            content=ft.ExpansionTile(
                icon_color=ft.colors.GREEN,
                collapsed_text_color=ft.colors.GREEN,
                collapsed_icon_color=ft.colors.GREEN,
                affinity=ft.TileAffinity.LEADING,
                visual_density=ft.VisualDensity.COMFORTABLE,
                maintain_state=True,
                initially_expanded=True,
                title=ft.RadioGroup(
                    value=data.filter_type,
                    content=ft.Row(
                        controls=[
                            ft.Radio(value="and", label="与"),
                            ft.Radio(value="or", label="或")
                        ]
                    )
                ),
                trailing=ft.IconButton(
                    icon=ft.Icons.DELETE_SWEEP,
                    tooltip="删除",
                    on_click=self.event_handler,
                    data={'event_name': 'delete'}
                ),

            ),
        )

        for index,sub_filter in enumerate(data.filter_content):
            col_container.content.controls.append(
                self.build_filter_content(sub_filter, level=level + 1)
            )
        return col_container
