[PeroPuri]

I'd like to create for my GUI an homepage like look, I've manege to arrive at this point, but now I'm little stuck. What I'd like to achieve is change the bottom_box when clicking the button that link to Page One or Page Two. Thanks for your help!

import tkinter as tk

class MainApp(tk.Frame):
    def __init__(self, parent, *args, **kwargs):
        tk.Frame.__init__(self, parent, *args, **kwargs)
        self.parent = parent

        
        ###MENU FRAME
        left_frame = tk.Frame(root, borderwidth=1, bg= "white", relief="solid", highlightthickness=2)
        left_frame.pack(side="left", expand=False, fill="y")
        container = tk.Frame(left_frame, borderwidth=1, bg= "white", relief="solid")
        container.pack(expand=True, fill="both", padx=5, pady=5)
        btn_1 = tk.Button(container, text="Home")
        btn_1.pack(padx=20, pady=20)
        btn_2 = tk.Button(container, text="Page One")
        btn_2.pack(padx=20,pady=20)
        
        ###TOP
        right_frame = tk.Frame(root, borderwidth=1, bg= "white", relief="solid", highlightthickness=2)
        right_frame.pack(side="right", expand=True, fill="both")
        top_box = tk.Frame(right_frame, borderwidth=1, bg= "white", relief="solid")
        top_box.pack(expand=True, fill="both", padx=10, pady=10)
        label_top = tk.Label(top_box, text="Title Logo", bg= "white")
        label_top.pack()
        
        ###BOTTOM
        bottom_box = tk.Frame(right_frame, borderwidth=1, bg= "white", relief="solid")
        bottom_box.pack(expand=True, fill="both", padx=10, pady=10)

        
if __name__ == "__main__":
    root = tk.Tk()
    root.geometry("1200x650")
    MainApp(root).pack(side="top", fill="both", expand=True)
    root.mainloop()
