    // how to remove a core menu entry by looping through the actions
    // already in the menu and finding the one you want by text label
    // once you have actions[i] you can use any of its properties/methods
    // such as actions[i].enabled = false instead of .visible

    // of an xtreewidget. Works the same way the main menu structure does
    var extraMenu = new QMenu();
    extraMenu.objectName = "extra.menu";
    extraMenu.name = "_extra";
    extraMenu.setTitle("Extras");
    pMenu.addMenu(extraMenu);
    // now that we have the menu we can add actions to it like we normally would
    var tmpaction = extraMenu.addAction(qsTr("Extra Menu"));
    tmpaction.setData("ExtraMenu");
    tmpaction.objectName = "em.extraMenu";
    tmpaction.enabled = true;
    // tmpaction.clicked.connect(yourFunctionHere);
    
    // incorporating @andersdd's snippet
    // contextually adding menu entries based on column contents
    if (pItem.rawValue("documenttype").toString() == "Invoice" && _list.id() > 0 ) {
      // do something with that pItem
    }
  }
}

Never Mind David, It's the delete on the right click. This is Great, this is just what I need to work on.
