I was wondering if there is a way in Folium to get the information on an entity we click on with Folium?

I'd like the map to either open a tab with the attribute information or just send back information on the entity selected without necessarily using a popup.


There seems to not be support for this in Folium as yet. Quoting from the issue regarding dynamically change/update markers:

"It's import(ant) to understand that folium generates the html with Leaflet javascript. So anything that happens on the map after generation is outside of folium's scope"

See here for more detail

  • Since posting this I found a work-around here (the work-around code is in the comment by @davidolmo on Feb 12). But also, there's a pull request that would seemingly resolve this, and it's under review at present here – Grizzly2501 Apr 10 at 5:38

You can use GeoJsonTooltip to show selected fields from a GeoDataFrame.

usmap = folium.Map(

    states[['STATE_NAME', 'geometry']].to_json(),
    style_function=lambda x: {
        'fillColor': 'lightblue',
        'color': 'black',
        'weight': 1,
    highlight_function=lambda x: {
        aliases=['State name:'],
  • Thank you for your answer, indeed i do use GeoJsonTooltip for looking at specific informations but what if I'd like to export the information of a specific area when clicking on an entity ? – Brocolus Feb 24 at 18:13
