如何使父项显示在下拉菜单中？

Question

使用pdoMenu创建了一个menu。每个父项也必须出现在下拉菜单中。例如，“Окомпании”必须包括“Окомпании”作为子菜单的第一个元素。有没有办法用pdoMenu做到这一点？

import numpy as np
from bokeh.plotting import Figure, show, curdoc
from bokeh.models import CustomJS, ColumnDataSource, Button, Column
from bokeh.events import Tap

cds = ColumnDataSource(data = dict(x = [0.1, 0.9], y = [0.1, 0.9]))
p = Figure(x_range = (0, 1), y_range = (0, 1), tools = "")
p.scatter(x = 'x', y = 'y', source = cds)

data = dict(x = [0.5], y = [0.5])
callback = CustomJS(args = {'cds': cds, 'data': data}, code = "cds.data = data")

button = Button(label = 'click me')
button.js_on_event('button_click', callback)

cds.js_on_change('data', CustomJS(code = "alert('data_change_detected');"))

show(Column(p, button))
