在我的 Tkinter gui 中，我能否让我的选项菜单只显示在一个选项卡上而不是所有三个选项卡上？

Question

I am programming a GUI with three tabs - each tab needs to have its own dropdown menu to select a financial calculation to compute. I have coded an options menu but it appears in all three tabs rather than one. How can I make an options menu exclusive to one tab? After trying to put the options menu in a frame my code looked like this:

import tkinter as tk
from tkinter import *

from tkinter import ttk

root = tk.Tk()
root.title("Tab Widget")
tabControl = ttk.Notebook(root)

variable = StringVar(root)
variable.set(OPTIONS[0])

w = OptionMenu(root, variable, *OPTIONS)
w.pack()

tab1 = ttk.Frame(tabControl, OPTIONS=["Gross Margin", "Operating Margin", "Net Profit Margin"])
tab2 = ttk.Frame(tabControl)
tab3 = ttk.Frame(tabControl)

tabControl.add(tab1, text='Tab 1')
tabControl.add(tab2, text='Tab 2')
tabControl.add(tab3, text='Tab 3')
tabControl.pack(expand=1, fill="both")

ttk.Label(tab1,
          text="Welcome to GeeksForGeeks").grid(column=0, row=0, padx=30, pady=30)
ttk.Label(tab2,
          text="Lets dive into the world of computers").grid(column=0, row=0, padx=30, pady=30)
ttk.Label(tab3,
          text="My third tab for my coursework").grid(column=0, row=0, padx=30, pady=30)

root.mainloop()

but I still get the error:

The following code moves the option menu in to tab 1.

import tkinter as tk
from tkinter import ttk

root = tk.Tk()
root.title("Tab Widget")
tabControl = ttk.Notebook(root)


tab1 = ttk.Frame(tabControl)
tab2 = ttk.Frame(tabControl)
tab3 = ttk.Frame(tabControl)

tabControl.add(tab1, text='Tab 1')
tabControl.add(tab2, text='Tab 2')
tabControl.add(tab3, text='Tab 3')
tabControl.pack(expand=1, fill="both")

OPTIONS=["Gross Margin", "Operating Margin", "Net Profit Margin"]
variable = tk.StringVar(root)
variable.set(OPTIONS[0])
w = tk.OptionMenu(tab1, variable, *OPTIONS)
w.grid(column=0,row=1)

ttk.Label(tab1,
          text="Welcome to GeeksForGeeks").grid(column=0, row=0, padx=30, pady=30)
ttk.Label(tab2,
          text="Lets dive into the world of computers").grid(column=0, row=0, padx=30, pady=30)
ttk.Label(tab3,
          text="My third tab for my coursework").grid(column=0, row=0, padx=30, pady=30)

root.mainloop()
