UPDATE 01.2021: You have to change NavigationLayout to MDNavigationLayout, and "lambda x: to "lambda x: nav_drawer.set_state("open")", your welcome :)

[brendanjensen]

5:00 toggle_nav_drawer() is depreciated, you can use set_state() and it has the same effect. At least in Dec 2020 :D

I want to add a toolbar which includes buttons to chance screens. The problem is, that I need the ScreenManager for the toolbar and for the multiple screens. How can I do this?

[nishanthkgr]

from kivymd.app import MDApp
from kivy.lang import Builder
from kivy.core.window import Window

Window.size = (300, 500)

navigation_helper = """
Screen:
NavigationLayout:
ScreenManager:
Screen:
BoxLayout:
orientation: 'vertical'
MDToolBar:
title: "Demo"
left_action_items : [['menu', lambda x :
elevation: 10

Widget:

MDNavigationDrawer:
id: nav_drawer
"""


class DemoApp(MDApp):

def build(self):
screen =

Hello sir I'm a student and working on a school project where I want to integrate this navigation drawer, but I always get an error whenever I write this code. I also tried the code in a single file where I wrote it as it is you have shown here, but still it gives the same error. Could you please help me in this. Waiting for your helpful reply.

[sunirnaychatterjee]

I am eagerly waiting for your every upcoming Videos bro 😇👍👍

[sweeterdeeker]

Can you show this using the Builder.load_file("file.kv") with Screen_Manager being involved for multiple screens? I am having difficulty.

[PercyleoYT]

I really appreciate that you do not use the kivi language .kv which in my opinion complicates things more ! Thanks for the tutorial !

[thunderstorm]

i am always waiting for new videos of kivymd and love to watch them thanks sir

[Shivam-edfn]

Sir I am writing your same code but I am getting this error ReferenceError: weakly-referenced object no longer exists....

[g_o_a_t]

some function of kivymd changed in new update so make sure your function names is correct

[OfficialAviatorMentors]

I am getting an Error of "too many indentation level" at the navigation_helper

[aavalos]

Change NavigationLayout to MDNavigationLayout. Also MDToolbar did not work. I changed it to MDTopAppBar for both top and bottom.
For Bottom Toolbar i used this code:
"...
MDBottomAppBar:
MDTopAppBar:
title: "Help"
...."
This worked for me.

[joeatlas]
