研究方向

首先閱讀現有的 LayerControl 實作和 issue 中提到的 map.get_root() 進入點,以及連結的先前 issue。確定如何在不需要自訂 JavaScript 或 CSS 的情況下,將 Python 提供的靜態 HTML 覆蓋層定位在地圖上方。完成的標準是該功能在產生的地圖輸出中正常運作,並支援所要求的固定位置內容。

描述

Is your feature request related to a problem? Please describe.
Is there a way to just insert some overlay into the map with custom html code? Like legend but with descriptions or titles and such?

Describe the solution you'd like
There are clearly the elements like Layer control, Minimaps and such that are overlaid in the map, so I feel like there should be a way to put some boxes there with some custom contents. The contents can be static (generated from python string)

I'd prefer to do it with just a python string passed to some python function, without the need to write js or css ourselves if possible.

Describe alternatives you've considered

  • I've tried to make a jinja template and put the html file contents in a template, but didn't work with the html made from the map being something that needs to be inside iframe.
  • I tried to edit the html myself, but the map is generated from javacript.
  • I tried to add the element in the map.get_root() but it puts that on top, and if I use css to make it a overlay (I'm not good with it), then it somehow ends up below the map and invisible.

Additional context
I went through some issues thinking it should be there but didn't find anywhere.

https://github.com/python-visualization/folium/issues/86 says there used to be a custom map template you could make but it's gone now.

Implementation
I'm not good with css or js, but I can do some python dev. If there is a easy way to just copy some parts from the LayerControl or such and add it, then I can help.
