ListViewDrag should be ListItemDrag in the API doc

[XiaoGuo, Liu]

https://developer.ubuntu.com/api/apps/qml/sdk-15.04.1/Ubuntu.Components.ViewItems/

  ViewItems.onDragUpdated: {
        if (event.status == ListViewDrag.Started) {
            if (event.from < 5) {
                // deny dragging on the first 5 element
                event.accept = false;

In the above code, the correct should be:

            ViewItems.onDragUpdated: {
                if (event.status == ListItemDrag.Started) {
                    if (event.from < 5) {
                        // deny dragging on the first 5 element
                        event.accept = false;
                    } else if (event.from >= 5 && event.from <= 10 &&
