Displaying Grouped Lists


Maybe this isn’t the right way to do this, but what if I wanted to display grouped lists. For example for the crimes group them by date with a title row? Would I need 3 lists? What kind of layout would I use, or would I add a layout to a layout?

Perhaps I’ve jumped ahead too much, but would appreciate ideas!
