I think you want these two options to be in a cascading menu like so: newmenu = Menu(filemenu) filemenu.add_cascade(label="New...", menu=newmenu) newmenu.add_command(label="Router") newmenu.add_command(label="Firewall") > filemenu.add_cascade(label="Router") > filemenu.add_cascade(label="Firewall") > filemenu.add_command(label="Open...", command = openFileDialog) > filemenu.add_separator() > filemenu.add_command(label="Exit", command = mainWindow.destroy) > > helpmenu = Menu(menubar) > menubar.add_cascade(label="Help", menu=helpmenu) > helpmenu.add_command(label="Online Help") > helpmenu.add_command(label="Help on the web") > helpmenu.add_separator() > helpmenu.add_command(label="About...", command = openAboutBox) > > Any ideas?? > > Miki Martin -- http://mail.python.org/mailman/listinfo/python-list
