Good afternoon, everyone
I am a beginner at making guis with tkinter and Python 3.6
I wanted to make a 'Quizlet' like interface for adding questions.
How can I make the next frame appear right below the one in which I clicked +?
What I also want is to have easily accessible datat structure fot the frames.
Thank you very much!

What I have tried:

Here is my code:

from tkinter import *
root = Tk()
height = root.winfo_screenheight()
canvas = Canvas(root, bd=0,width=800,height=height,bg = "blue")
screen_fit = height/105
frame_number = 2
EDIT_QUESTIONS= Label(root,text="Edit questions",font = "Courier").grid(row = 1,column = 1)
class edit:
    def __init__(self):
       canvas.grid(row=2,column=2)
       self.new_frame()
    def new_frame(self):
        def remove(window):
            pass
        def new_frame1(self):
            global frame_number
            
            frame = Frame(root)
            r = (10 + 105)* (frame_number -1)
            frame_number =  frame_number + 1
            window = canvas.create_window(25, r , anchor = "nw", window = frame,tags =(frame_number))
            text = Text(frame,height = 2)
            text.grid(row=1,column=2)
            plus = Button(frame,text="+",command = self.new_frame)
            plus.grid(row=2,column=1)            
            minus = Button(frame,text="-" )
            #minus.config(command = lambda: remove(window))
            minus.grid(row=3,column=1)

            if frame_number > int(screen_fit)or frame_number == int(screen_fit):
                def on_mousewheel(event):
                    canvas.yview_scroll(-1*(int(event.delta/120)), "units") 

                scrollbar= Scrollbar(root,orient="vertical",command=canvas.yview)
                scrollbar.grid(row=2,column=4,sticky = "ns")
                canvas.bind_all("<MouseWheel>", on_mousewheel)
                canvas.configure(scrollregion=canvas.bbox("all"),width=800,height=700) 
                canvas.configure(yscrollcommand=scrollbar.set)
        new_frame1(self)
Edit = edit()
