It sounds like you want a Nested Menu.

enter image description here

One way to do that in Qt is to use a QToolButton with a QMenu

d = {'a': [1,2,3], 'b': [4,5,6], 'c': [7,8,9]}

button = QToolButton()

def callback_factory(k, v):
    return lambda: button.setText('{0}_{1}'.format(k, v))

menu = QMenu()
for k, vals in d.items():
    sub_menu = menu.addMenu(k)
    for v in vals:
        action = sub_menu.addAction(str(v))
        action.triggered.connect(callback_factory(k, v))

button.setMenu(menu)
