Assignment Task: Selecting a Restaurant
When the selected restaurant is changed, the following requirements must be met:
1. If there is a current order with items in it, a prompt should be displayed to the user to confirm whether they want to clear the order or not. If the user does not want to clear the order, then no data on the page should change (i.e., it cancels the affect of the change in restaurant).
2. If the user accepts clearing the current order or if there is no current order then the newly selected restaurants information should be placed on the page. Any information from the previous restaurant should be removed. Any existing order information should be cleared.
3. The restaurant's name, minimum order and delivery fee should be displayed near the top of the page.
4. The menu and order information should be displayed in a three-column layout below the basic restaurant information. The left column must have a list of the categories in the restaurant's menu. These categories should also be links to allow the user to skip directly to that category within the menu. The middle column should present the menu of the restaurant (see Menu Requirements below). The right column should present the current order summary (see Order Summary Requirements below).
