Emma found this one when ordering from Oregano pizza online. it’s quite a simple but cool feature for ordering a pizza.
I’ve attempted to capture it in an animated gif (first one I’ve made). After choosing a pizza, the toppings on that pizza are checked automatically. This makes it very easy to see what’s included on the pizza and then customise to your liking, checking or I unchecking toppings as you wish.
This approach of designing for customisation and alterations makes it very easy to get the exact pizza you want. I think Oregano knew that people liked to make changes to pizza toppings and added this as a primary scenario.
