A collection of Plotly figure templates with a Bootstrap theme

Project description

Dash Bootstrap Templates

See these features live at :

dash-bootstrap-templates library provides:

  • Bootstrap themed Plotly figure templates. You will find a Plotly template for each of the 26 Bootstrap/Bootswatch themes available in the Dash Bootstrap Components Library. These templates will automatically style your figures with Bootstrap theme colors and fonts.

  • Two All-in-One components to change themes in a Dash app.

    • ThemeSwitchAIO toggles between two themes.
    • ThemeChangerAIO select from multiple themes.
  • The dbc.css stylesheet which styles Dash Core Components and the Dash DataTable with a Bootstrap theme.

Note: The ThemeSwitchAIO and ThemeChangerAIO components and the dbc.css stylesheet requires Dash Bootstrap Components>=V1.0.0. It will only work with the themes included in Dash Bootstrap Components>=V1.0.0.

The Bootstsrap themed Plotly figure templates can be used with any Plotly figure. It does not require Dash or the Dash Bootstrap Components library.

Figure Template Quickstart

pip install dash-bootstrap-templates

A sample of 8 of the 26 Bootstrap themed Plotly figure templates available
in the dash-bootstrap-template library

from dash import Dash, html, dcc
import dash_bootstrap_components as dbc
from dash_bootstrap_templates import load_figure_template
import as px

df =

templates = [


figures = [
        title="Gapminder 2007: '%s' theme" % template,
    for template in templates

app = Dash(__name__, external_stylesheets=[dbc.themes.BOOTSTRAP])

app.layout = dbc.Container([dcc.Graph(figure=fig, className="m-4") for fig in figures])

if __name__ == "__main__":

dbc.css stylesheet

The dash-core-components, the Dash DataTable and Plotly figures are not automatically styled with a Bootstrap theme. An easy way to make your Dash components look better with a Bootstrap theme is to use the stylesheet from the dash-bootstrap-templates library. This stylesheet defines the "dbc" class.

Adding className="dbc" minimally styles Dash components with your selected Bootstrap theme:

  • Makes the text readable in both light and dark themes.
  • Uses theme's font-family.
  • Changes the accent color to the theme's primary color

You can add the dbc class as an external stylesheet like this:

dbc_css = ("")
app = dash.Dash(__name__, external_stylesheets=[dbc.themes.BOOTSTRAP, dbc_css])

Add className="dbc" to the outer container of the app or a component like this:

app.layout = dbc.Container(

That's it! Simply adding className="dbc" will make Dash Core Components and the DataTable look better with ALL themes included in the dash-bootstrap-components library.

Theme Switcher Components

See a live demo at

dash-bootstrap-templates has two All-in-One components to change themes. The ThemeSwitchAIO is a switch with icons on the left and right, which is ideal for toggling between a light and a dark theme. The ThemeChangerAIO has a button that opens an dbc.Offcanvas component which by default shows all the available themes.

Note the All-in-One component switches the Bootstrap stylesheet for the app and sets the default Plotly figure template for the theme, however, figures must be updated in a callback in order to render the figure with the new template. See the callback below for an example. The template_from_url is a helper function that returns the template name based on the theme url. For example template_from_ur(dbc.themes.SLATE) returns "slate"

ThemeChangerAIO Quickstart

from dash import Dash, dcc, html, Input, Output
import pandas as pd
import as px
import dash_bootstrap_components as dbc
from dash_bootstrap_templates import ThemeChangerAIO, template_from_url

dbc_css = (
app = Dash(__name__, external_stylesheets=[dbc.themes.BOOTSTRAP, dbc_css])

df = pd.DataFrame(
        "Fruit": ["Apples", "Oranges", "Bananas", "Apples", "Oranges", "Bananas"],
        "Amount": [4, 1, 2, 2, 4, 5],
        "City": ["SF", "SF", "SF", "Montreal", "Montreal", "Montreal"],
header = html.H4(
    "ThemeChangerAIO Demo", className="bg-primary text-white p-4 mb-2 text-center"
buttons = html.Div(
        dbc.Button("Primary", color="primary"),
        dbc.Button("Secondary", color="secondary"),
        dbc.Button("Success", color="success"),
        dbc.Button("Warning", color="warning"),
        dbc.Button("Danger", color="danger"),
        dbc.Button("Info", color="info"),
        dbc.Button("Light", color="light"),
        dbc.Button("Dark", color="dark"),
        dbc.Button("Link", color="link"),
graph = html.Div(dcc.Graph(id="graph"), className="m-4")

app.layout = dbc.Container(
                dbc.Col(ThemeChangerAIO(aio_id="theme", radio_props={"value":dbc.themes.FLATLY}), width=2,),
                dbc.Col([buttons, graph],width=10),
    className="m-4 dbc",

    Output("graph", "figure"), Input("theme"), "value"),
def update_graph_theme(theme):
        df, x="Fruit", y="Amount", color="City", barmode="group", template=template_from_url(theme)

if __name__ == "__main__":


Here is the same app, but using a the ThemeSwitchAIO component to toggle between two themes. See the (code here).

It's also possible to change the icons. See an example of using Bootstrap icons instead of the default FontAwesome icons here.



Dash Labs is Plotly library that explores new features for future releases of Dash. In Dash Labs V0.4.0, there was a cool feature where Bootstrap themed figure templates were created "on the fly". This was a part of the layout templates project that is no longer being developed.

Even though these Bootstrap themed figure templates will not be included in Dash, the dash-bootstrap-templates makes them available to you. The figure templates are created using the Dash Labs' algorithms and saved in json format. When you use load_figure_template() in your app, it loads the json file, adds it to and sets it as the default figure template for an app. See more information about Plotly figure templates here.

Available Themes

This library provides a figure template for the following Bootstrap/Bootswatch themes:

valid_themes = [ "bootstrap", "cerulean", "cosmo", "flatly", "journal", "litera", "lumen", "lux", "materia", "minty", "pulse", "sandstone", "simplex", "sketchy", "spacelab", "united", "yeti", "cyborg", "darkly", "slate", "solar", "superhero", "morph", "quartz", "vapor" "zephyr" ]

ThemeChangerAIO Reference

ThemeChangerAIO is an All-in-One component composed of a parent html.Div with the following components as children:

  • dbc.Button ("switch") Opens the Offcanvas component for user to select a theme.
  • dbc.Offcanvas ("offcanvas")
  • dbc.RadioItems ("radio"). The themes are displayed as RadioItems inside the dbc.Offcanvas component. The value is a url for the theme
  • html.Div is used as the Output of the clientside callbacks.

The ThemeChangerAIO component updates the stylesheet when the value of radio changes. (ie the user selects a new theme)

  • param: radio_props A dictionary of properties passed into the dbc.RadioItems component. The default value is dbc.themes.BOOTSTRAP
  • param: button_props A dictionary of properties passed into the dbc.Button component.
  • param: offcanvas_props. A dictionary of properties passed into the dbc.Offcanvas component
  • param: aio_id The All-in-One component ID used to generate components' dictionary IDs.

The All-in-One component dictionary IDs are available as:

  • ThemeChangerAIO.ids.offcanvas(aio_id)
  • ThemeChangerAIO.ids.button(aio_id)

ThemeSwitchAIO Reference

ThemeSwitchAIO is an All-in-One component composed of a parent html.Div with the following components as children:

  • dbc.Switch ("switch") with icons to the left and right of the switch.
  • dcc.Store ("store") The themes are stored in the data prop.
  • html.Div is used as the Output of the clientside callbacks.

The ThemeSwitchAIO component updates the stylesheet when triggered by changes to the value of switch or when the themes are updated in the "store" component. The themes in the switch may be updated in a callback by changing the theme urls in the "store" component.

  • param: themes A list of two urls for the external stylesheets. The default is [dbc.themes.CYBORG, dbc.themes.BOOTSTRAP].
  • param: icons A dict of the icons to the left and right of the switch. The default is
    {"left" :"fa fa-moon", "right" :"fa fa-sun"}.
  • param: aio_id The All-in-One component ID used to generate component's dictionary IDs.

The All-in-One component dictionary IDs are available as

  • ThemeSwitchAIO.ids.switch(aio_id)
