Different delegates for QML ListView

I’ve had the same problem, the Qt documentation is providing a pretty good answer: http://doc.qt.io/qt-5/qml-qtquick-loader.html#using-a-loader-within-a-view-delegate

The easiest solution is an inline Component with a Loader to set a source file:

ListView {
    id: contactsView
    anchors.left: parent.left
    anchors.top: parent.top
    width: parent.width
    height: parent.height
    orientation: Qt.Vertical
    spacing: 10
    model: contactsModel
    delegate: Component {
        Loader {
            source: switch(position) {
                case "Engineer": return "Employee.qml"
                case "Manager": return "Manager.qml"
            }
        }
    }
}

Any attempt to use Loader.srcComponent will result in missing any variable from the model (including index). The only way for the variables to be present is the children Component to be inside the main Component, but then only one can be present, so it is useless.
