将 folium 地图上的菜单栏添加到 select 或 deselect 特定对象（标记）

Question

我制作了一张很酷的地图，如下图所示，但包含更多对象。

import folium

base_map = folium.Map(location=[52.2297, 21.0122], control_scale=True, zoom_start=10)

points1 = [(52.228771, 21.003146),

       ( 52.238025, 21.050971),
       (52.255008, 21.036172),
       (52.252831, 21.051385),
       (52.219995, 20.965021)]

for tuple_ in points1:

    icon=folium.Icon(color='white', icon='train', icon_color="red", prefix='fa')
    folium.Marker(tuple_, icon=icon).add_to(base_map)

points2 = [(52.239062, 21.131601),

       (52.204905, 21.168202),
       (52.181296, 20.987486),
       (52.206272, 20.914988),
       (52.254395, 21.224107)]

for tuple_ in points2:
    icon=folium.Icon(color='white', icon='car', icon_color="blue", prefix='fa')
    folium.Marker(tuple_, icon=icon).add_to(base_map)

line_points = [(52.204905, 21.168202),(52.255008, 21.036172), (52.219995, 20.965021), (52.239062, 21.131601), (52.254395, 21.224107)]

folium.PolyLine(locations=line_points, weight=3,color = 'yellow').add_to(base_map)


base_map.save("example_map.html")

结果：

问：我想知道是否有一种方法可以构建某种菜单栏，使 select 地图中的特定对象成为可能。例如只有汽车，只有火车或汽车和黄线。

它不会成为任何网站的一部分 - 只是一个合并到 .html 文件中的解决方案，如下面的

感谢帮助！！
