Hi All,  
I’m trying to create a multi-page app,  
 ![image](https://us1.discourse-cdn.com/flex024/uploads/plot/original/2X/6/680aa702d6ffb3618f3d610073bffee2d043a7c5.png)

and I would like to refresh page content( also dataframe) on refresh, I have followed [https://dash.plot.ly/live-updates](https://dash.plot.ly/live-updates) but for some reason its not updating.

Can someone please help me or guide me in the right direction.

Below are the codes, Thanks in advance

app.py

```auto
import dash

app = dash.Dash( __name__ , meta_tags=[{"name": "viewport", "content": "width=device-width"}])
server = app.server
app.config.suppress_callback_exceptions = True

```

index.py

```auto
import dash_core_components as dcc
import dash_html_components as html
from dash.dependencies import Input, Output

# Import app
from app import app

# Import Pages
from page1 import *
from page2 import *

#import menu
from menu import menu
menu = menu()

def serve_layout():
    return html.Div(
        [
            dcc.Location(id = 'url', refresh = False),
            html.Div(id = 'page-content')
        ]
    )

app.layout = serve_layout

# Index Callbacks-------------------------------------------------------------------------------------------------------
@app.callback(Output('page-content', 'children'),[Input('url', 'pathname')])
def display_page(pathname):
    if pathname == '/page2':
        return html.Div([menu,page2_layout])
    elif pathname in ["/", "/page1"]:
        return html.Div([menu,page1_layout])
    # If the user tries to reach a different page, return a 404 message
    return html.Div(
        [
            menu,
            html.Div(
                [
                    html.H1("404: Not found", className="text-danger"),
                    html.Hr(),
                    html.P(f"The pathname {pathname} was not recognised..."),
                ]
            )
        ]
    )

if __name__ == ' __main__':
    app.run_server(debug=True)

```

page1.py

```auto
import dash_core_components as dcc
import dash_html_components as html
import datetime

page1_layout = html.Div(
    [
        html.H1('The time is: ' + str(datetime.datetime.now())),
        html.P('this is page 1!')
    ],
    className='main_content'
)

```

page2.py

```auto
import dash_core_components as dcc
import dash_html_components as html
import datetime
import pandas as pd

filepath = 'test.csv'

#imported dataframe
test_df = pd.read_table(filepath)

page2_layout = html.Div(
    [
        html.H1('The time is: ' + str(datetime.datetime.now())),
        html.P('this is page 2!')
    ],
    className='main_content'
)

```

menu.py

```auto
import dash_html_components as html
import dash_core_components as dcc

def menu():
    return html.Div(
        id="app_heading",
        className="class_app_heading",
        children=[
            html.Div(
                id="app_logo",
                children=[
                    html.Img(src='/assets/logo.png')
                ],
            ),
            html.Div(
                id="app-menu",
                className="class_app_menu",
                children=[
                    dcc.Link('Page1',
                             href='/page1',
                             id='id_page_1',
                             className='active'
                             ),
                    dcc.Link('Page2',
                             href='/page2',
                             id='id_page_2',
                             ),
                ],
            ),
        ],
    )
