This is a school project, and we have uml to follow. The problem is when i try to code first, i dont know how to add gui for it. But when i try to design the gui first, i cant follow the uml?
I’m having a hard time on how to read csv, that shows the list of items in gui, like I have MENU, and categories like, Rice Meal, Drinks, Desserts, Snacks. When Rice Meal button is click, it should show the list and can also add the item you pick to order.

I hope you get what I mean TT.

I tried adding table, but don’t know if you can add item from table to the order, also item are not from csv, I just write it up.
