1> set top mode display when click overflow display area
which will be shown error as follow

throw FlutterError.fromParts([
ErrorSummary('Duplicate GlobalKey$s detected in widget tree.'),
// TODO(jacobr): refactor this code so the elements are clickable
// in GUI debug tools.

            ErrorDescription(
              'The following GlobalKey$s $were specified multiple times in the widget tree. This will lead to '
              'parts of the widget tree being truncated unexpectedly, because the second time a key is seen, '
              'the previous instance is moved to the new location. The key$s $were:\n'
              '- ${keyLabels.join("\n  ")}\n'
              'This was determined by noticing that after$the widget$s with the above global key$s $were moved '
              'out of $their$respective previous parent$s2, $those2 previous parent$s2 never updated during this frame, meaning '
              'that $they either did not update at all or updated before the widget$s $were moved, in either case '
              'implying that $they still $think that $they should have a child with $those global key$s.\n'
              'The specific parent$s2 that did not update after having one or more children forcibly removed '
              'due to GlobalKey reparenting $are:\n'
              '- ${elementLabels.join("\n  ")}'
              '\nA GlobalKey can only be specified on one widget at a time in the widget tree.',
            ),
          ]);

2. click last item expander can not work onTap event

I don't know how to use the navigation View for menu paneitem and group the paneItem

Could you enhance the example case where have PaneItemExpander menu Item ?
