# Numeric Input Examples and Reference

# Default Numeric Input

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

    using Dash
    using DashDaq

    external_stylesheets = ["https://codepen.io/chriddyp/pen/bWLwgP.css"]

    app = dash(external_stylesheets=external_stylesheets)

    app.layout = html_div([
      daq_numericinput(
          id="my-numeric-input",
          value=0
      ),
      html_div(id="numeric-input-output")
    ])

    callback!(app,
      Output("numeric-input-output", "children"),
      [Input("my-numeric-input", "value")]) do value
      return "The value is $value."
    end

    run_server(app, "0.0.0.0", debug=true)

The value is 0.

### Label

Set the label and label position with `label` and `labelPosition`.

    using Dash
    using DashDaq

    app = dash()

    app.layout = daq_numericinput(
      label="Label",
      labelPosition="bottom",
      value=10,
    )

    run_server(app, "0.0.0.0", debug=true)

Label

### Size

Extend the size with `size`.

    using Dash
    using DashDaq

    app = dash()

    app.layout = daq_numericinput(
      value=10,
      size=120
    )

    run_server(app, "0.0.0.0", debug=true)

### Max and Min

Set the minimum and maximum bounds with `min` and `max`.

    using Dash
    using DashDaq

    app = dash()

    app.layout = daq_numericinput(
        min=0,
        max=100,
        value=20
    )

    run_server(app, "0.0.0.0", debug=true)

### Disable

Disable the numeric input by setting `disabled=`

    using Dash
    using DashDaq

    app = dash()

    app.layout = daq_numericinput(
      disabled=true,
      min=0,
      max=10,
      value=2
    )

    run_server(app, "0.0.0.0", debug=true)

## NumericInput Properties

> Our recommended IDE for writing Dash apps is Dash Enterprise's Data Science Workspaces, which has typeahead support for Dash Component Properties. Find out if your company is using Dash Enterprise.

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

`value` (Real; optional): The value of numeric input.

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

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

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

`disabled` (Bool; optional): If true, numeric input cannot changed.

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

`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:

- `label` (String; optional)

- `style` (Dict; optional)

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

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

`style` (Dict; default `{ display: 'flex', justifyContent: 'center' }`): Style to apply to the root component element.

`persistence` (Bool | String | Real; 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` (Array 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.
