dropdown menu KivyMD not opening

When I try to open my dropdown menu nothing happens here is the python code:

from kivy.lang import Builder
from kivy.uix.boxlayout import BoxLayout
from kivymd.app import MDApp
from kivymd.uix.menu import MDDropdownMenu
from kivy.properties import ObjectProperty


class app(MDApp):
    dropdown = ObjectProperty
    
    def print(self):
        print("pressed!")
    
    def on_start(self):
        self.dropdown = MDDropdownMenu()

        self.dropdown.items.append({"viewclass":"MDMenuItem","text":"Option 1"})
    
    def build(self):
        return Builder.load_file("main.kv")
    


app().run()

Here is the .kv file:

MDBoxLayout:
    orientation: "vertical"

    MDToolbar:
        title: "MDToolbar"
        left_action_items: [["menu", lambda x: app.dropdown.open()]]


    MDLabel:
        text: "Content"
        halign: "center"

I hope that someone whos knows what they are doing can help me because I need it. Thank you in advance.

I believe you must provide a caller for the MDDropdownMenu, which is used to position the MDDropdownMenu. If you add an id for the MDToolBar in your kv:

MDToolbar:
    id: toolbar
    title: "MDToolbar"
    left_action_items: [["menu", lambda x: app.dropdown.open()]]

Then you can provide a caller like this:

    self.dropdown = MDDropdownMenu(caller=self.root.ids.toolbar.ids.left_actions)
