Grouping Items in a ListView Control
You can group the items that appear in a ListView control. For example, instead of displaying a flat list of products, you can group products by product category (see Figure 8.13).
FIGURE 8.13 Grouping ListView items
If you want to take advantage of groups, then you need to create a grouped data source. You create a grouped data source by calling the WinJS.Binding.List createGrouped() method.
The code in Listing 8.13 and Listing 8.14 illustrates how you can use the createGrouped() method to group products by categories.
