Hello, this is a car rental program using Tkinter Gui with Python. I want to be able to integrate a scrollbar for the car model area (under settings), where users get to pick from the options listed when they type the car make. For example, when user enters "Tesla", the options for Tesla models pop up under the car model scrollbar, so they can choose what they are looking for, instead of having the user to type out the model. Could you please show me a code example of how it's done? Thanks!

Here is my program so far:
