Add drop down list from geojson, csv files from Ipywidgets module using PYTHON

Question

I am badly stuck with the problem of creating a drop-down list using Ipywidgets in python with files (JSON,GEOJSON,CSV)

m = geemap.Map() url = "C:/Users/Hp/Desktop/New_SoilDB_RAW.geojson"

m.add_point_layer(url, popup=["DISTRICTS", "Soil"], layer_name="Soil") m

choose option

from ipywidgets import VBox, Label, Dropdown, Output

desc = Label("C:/Users/Hp/Desktop/New_SoilDB.csv")

dropdown = Dropdown( options=['Soil', 'DISTRICTS', 'LAT', 'LONG'], value='clay','Karimnagar',, disabled=False)

output = Output()

dropdown.observe(generate_plot, names="value")

VBox([desc, dropdown, output])

enter image description here

I am confused how to deal with the issue and any seek help. Thanks in advance

Answer 1

It's not clear what your error is, can you please include any error messages including the full stack trace.

I can see straight away that 'clay' is not one of your listed options for your Dropdown.

dropdown = Dropdown( options=['Soil', 'DISTRICTS', 'LAT', 'LONG'], value='Soil', disabled=False)
