Grouped ListView

I would like to show a ListView of items grouped by their categories. The category for the item is stored as a string under the Items collection. For example, this is how it would appear:

DATA:
ITEM | CATEGORY
Apples|Produce
Eggs|Dairy
Bananas|Produce
Milk|Dairy

LISTVIEW DESIRED:
PRODUCE
Apples
Bananas
DAIRY
Eggs
Milk
