Numeric Input Examples and Reference


Default Numeric Input

An example of a default numeric input without any extra properties.

import dash
from dash.dependencies import Input, Output
import dash_daq as daq
import dash_core_components as dcc
import dash_html_components as html

app = dash.Dash(__name__)

app.layout = html.Div([
    daq.NumericInput(
        id='my-numeric-input-1',
        value=0
    ),
    html.Div(id='numeric-input-output-1')
])


@app.callback(
    Output('numeric-input-output-1', 'children'),
    Input('my-numeric-input-1', 'value')
)
def update_output(value):
    return 'The value is {}.'.format(value)


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

Label

Set the label and label position with label and labelPosition.

import dash_daq as daq

daq.NumericInput(
    label='Label',
    labelPosition='bottom',
    value=10,
)

Size

Extend the size with size.

import dash_daq as daq

daq.NumericInput(
    value=10,
    size=120
)

Max and Min

Set the minimum and maximum bounds with min and max.

import dash_daq as daq

daq.NumericInput(
    min=0,
    max=100,
    value=20
)

Disable

Disable the numeric input by setting disabled=True julia true

import dash_daq as daq

daq.NumericInput(
    disabled=True,
    min=0,
    max=10,
    value=2
)

id (string; optional):
The ID used to identify this compnent in Dash callbacks.

className (string; optional):
Class to apply to the root component element.

disabled (boolean; optional):
If True, numeric input cannot changed.

label (dict; optional):
Description to be displayed alongside the control. To control styling,
pass an object with label and style properties.

label is a string | dict with keys:

labelPosition (a value equal to: ‘top’ or ‘bottom’; default 'top'):
Where the numeric input label is positioned.

max (number; default 10):
The maximum value of the numeric input.

min (number; default 0):
The minimum value of the numeric input.

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 (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.

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.

size (number; optional):
The size (length) of the numeric input in pixels.

style (dict; optional):
Style to apply to the root component element.

theme (dict; default light):
Theme configuration to be set by a ThemeProvider.

value (number; optional):
The value of numeric input.
