Dear Sam,
I am trying to build the dash in a different way. On one page I want to put the dropdown and on other I want to display the tabs.
For this purpose, I came across an example, where there are two pages.
import dash
import dash_core_components as dcc
import dash_html_components as html
print(dcc.__version__) # 0.6.0 or above is required
external_stylesheets = ['https://codepen.io/chriddyp/pen/bWLwgP.css']
app = dash.Dash(__name__, external_stylesheets=external_stylesheets)
app.config.suppress_callback_exceptions = True
app.layout = html.Div([
dcc.Location(id='url', refresh=False),
html.Div(id='page-content')
])
index_page = html.Div([
dcc.Link('Go to Page 1', href='/page-1'),
html.Br(),
dcc.Link('Go to Page 2', href='/page-2'),
])
page_1_layout = html.Div([
html.H1('Page 1'),
dcc.Dropdown(
id='page-1-dropdown',
options=[{'label': i, 'value': i} for i in ['LA', 'NYC', 'MTL']],
value='LA'
),
html.Div(id='page-1-content'),
html.Br(),
dcc.Link('Go to Page 2', href='/page-2'),
html.Br(),
dcc.Link('Go back to home', href='/'),
])
@app.callback(dash.dependencies.Output('page-1-content', 'children'),
[dash.dependencies.Input('page-1-dropdown', 'value')])
def page_1_dropdown(value):
return 'You have selected "{}"'.format(value)
page_2_layout = html.Div([
html.H1('Page 2'),
dcc.RadioItems(
id='page-2-radios',
options=[{'label': i, 'value': i} for i in ['Orange', 'Blue', 'Red']],
value='Orange'
),
html.Div(id='page-2-content'),
html.Br(),
dcc.Link('Go to Page 1', href='/page-1'),
html.Br(),
dcc.Link('Go back to home', href='/')
])
@app.callback(dash.dependencies.Output('page-2-content', 'children'),
[dash.dependencies.Input('page-2-radios', 'value')])
def page_2_radios(value):
return 'You have selected "{}"'.format(value)
# Update the index
@app.callback(dash.dependencies.Output('page-content', 'children'),
[dash.dependencies.Input('url', 'pathname')])
def display_page(pathname):
if pathname == '/page-1':
return page_1_layout
elif pathname == '/page-2':
return page_2_layout
else:
return index_page
if __name__ == '__main__':
app.run_server(debug=False,port=1244,host = '0.0.0.0')
In this code, on page 2, there are Radio buttons. What I want is that Page 1 remains as it is to display on Page 2 'You selected Value". That is the value selected on page 1. That is to remove the radio buttons and bring the value selected on Page 1 to Page 2.
Please help me with this.
