Drag and drop targets to one target, in a specific order.

Hi Jennifer,

You can do it in several ways.
One is to create multiple slides for creating a series drag&drop, since it has specific order, it means there is only one correct drop for one slide. Jump to next slide when dropping correctly, show incorrect layer when dropping incorrect.

Another way is to use the state of pizza as a condition. For example: if the correct matching is:
item1>>pizza (normal state)
item2>>pizza1(state for item1 is added)
item3>>pizza12 (state for item1&2 are added)

Show incorrct layer when item2 drops on the pizza if the state of the pizza is Not pizza1.
Show incorrct layer when item3 drops on the pizza if the state of the pizza is Not pizza12.
Change the state of the pizza to pizza1 when item1 drops on pizza if the state of the pizza is normal.
Change the state of the pizza to pizza12 when item2 drops on pizza if the state of the pizza is pizza1.
Change the state of the pizza to pizza123 when item3 drops on pizza if the state of the pizza is pizza12.
