I’m new to kivy and want to create a small app. Which will show different text (loaded from the database).
I tried to make a BoxLayout, but it is very difficult, especially since I then have to access the id in this element. I think I took a little wrong turn.

py code

import kivy
from kivy.uix.label import Label
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
class Container(BoxLayout):
    def __init__(self, **kwargs):
        super(Container, self).__init__(**kwargs)
        w=BoxLayout()
        self.ids.tr.add_widget(w)
        
class MyApp(App):
    def build(self):
        return Container()


if __name__ == '__main__':
    MyApp().run()

kv code

<container>:
    orientation:"vertical"
    Label:
        text: "Plan"
    BoxLayout:
        id:tr
        Label
            id: id1
            text: "text1"
        Label:
            id: id2
            text: "text2"
        Label:
            id: id3
            text: "text3"

I would like something like this: [] 1
