   \inherits Rectangle
   \inqmlmodule StatusQ.Components
   \since StatusQ.Components 0.1
   \brief It allows to add items and display them as a tag item with an image and text. It also allows to store and display logical `and` / `or` operators into the list. Inherits \l{https://doc.qt.io/qt-6/qml-qtquick-rectangle.html}{Item}.

   The \c StatusNetworkSelector is populated with a data model. The data model is commonly a JavaScript array or a ListModel object with specific expected roles.

   Example of how the component looks like:
   \image status_item_selector.png

   Example of how to use it:
   \qml
        StatusNetworkSelector {
            id: networkSelector

            title: "Network preference"
            enabled: addressInput.valid
            defaultItemText: "Add networks"
            defaultItemImageSource: "add"

            itemsModel: ListModel {}

            addButton.onClicked: {
            }

            onItemClicked: {
            }

            onItemRightButtonClicked: {
            }
        }
   \endqml
