Toggle Switch Examples and Reference

Default Toggle Switch

An example of a default toggle switch without any extra properties.

from dash import Dash, html, Input, Output, callback
import dash_daq as daq

app = Dash(__name__)

app.layout = html.Div([

    Output('my-toggle-switch-output', 'children'),
    Input('my-toggle-switch', 'value')
def update_output(value):
    return f'The switch is {value}.'

if __name__ == '__main__':

Vertical orientation

Make the switch display vertically by setting vertical=True.

import dash_daq as daq


Adjust the size of the toggle switch with size.

import dash_daq as daq


Add a label to the toggle switch and specify its position using label and labelPosition.

import dash_daq as daq
    label='My toggle switch',

persistence (boolean | string | number; optional):
Used to allow user interactions in this component to be persisted when
the component - or the page - is refreshed. If persisted is truthy
and hasn’t changed from its previous value, a value that the user
has changed while using the app will keep that change, as long as the
new value also matches what was given originally. Used in
conjunction with persistence_type.

persisted_props (list of values equal to: ‘value’; default ['value']):
Properties whose user interactions will persist after refreshing the
component or the page. Since only value is allowed this prop can
normally be ignored.

persistence_type (a value equal to: ‘local’, ‘session’ or ‘memory’; default 'local'):
Where persisted user changes will be stored: memory: only kept in
memory, reset on page refresh. local: window.localStorage, data is
kept after the browser quit. session: window.sessionStorage, data is
cleared once the browser quit.
