How to select lines(multiple line) in Tree widget?

[Yurii-huang]

The partitions vdc1,2,3,4 and vdd1 setting a name's 'vg' physical volume(think of them as a whole)
When I select any partition, completes all partition rows that contain 'vg' in the selection.
What should I do？

Thanks to anyone

This should be a style drawing issue, and I don't seem to see the API for multiple select rows. If there is no API, just tell me where(method) to redraw the line to select the style

overload

def render_label(
        self, node: TreeNode[TreeDataType], base_style: Style, style: Style
    ) -> Text:


    if # about node conditional expressions
                    node_label.append(raid, Style(bgcolor=Color.from_rgb(0,95,0)))
                else:
                    node_label.append(raid, style=node_label.style)
