How to create Drop-Down Menu in python (method_I).

here we will be learning a dropdown menu to select one out of many, like month or week day.

In this section we will be using OptionMenu.

below is the code to design a drop down menu to select day of the week.

 #program
 try:
     from Tkinter import *
 except:
     from tkinter import *

 #Defining option list
 OptionList = [
 "Sunday",
 "Monday",
 "Tuesday",
 "Wednesday",
 "Thursday",
 "Friday",
 "Saturday",
 ]
 mw = Tk()
 #Font and orientation setup
 mw.geometry('400x60+50+50')
 mw.title("AETies: Automation Expert Technologies")
 var = StringVar(mw)
 var.set(OptionList[0])

 #Label
 labelTest = Label(mw,text="select day", fg='red')
 labelTest.pack(side="top")

 opt = OptionMenu(mw, var, *OptionList)
 opt.config(width=20, font=('Helvetica', 12))
 opt.pack(side="top")

 mainloop()

let's collect the value from OptionMenu

 #program

 try:
     from Tkinter import *
 except:
     from tkinter import *

 #Defining option list
 OptionList = [
 "Sunday",
 "Monday",
 "Tuesday",
 "Wednesday",
 "Thursday",
 "Friday",
 "Saturday",
 ]
 mw = Tk()
 #Font and orientation setup
 mw.geometry('400x60+50+50')
 mw.title("AETies: Automation Expert Technologies")
 variable = StringVar(mw)
 variable.set(OptionList[0])

#Label
 labelTest = Label(mw,text="select day", fg='red')
 labelTest.pack(side="top")

 opt = OptionMenu(mw, variable, *OptionList)
 opt.config(width=20, font=('Helvetica', 12))
 opt.pack(side="top")

#Function
 def callback(*args):
     labelTest.configure(text="The selected item is {}".format(variable.get()))
 variable.trace("w", callback)
 mainloop()
