Quickstart


To get started, simply add the Yada() component to the app's layout. You will see the Yada icon, a helpdesk, in the top right corner. On hover, it displays a default welcome message.

yada_quickstart

import dash
from dash import html
import dash_bootstrap_components as dbc
from dash_yada import YadaAIO

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

app.layout = dbc.Container(
    [
        YadaAIO(yada_id="yada"),
        html.H4("My Dashboard", className="p-3 bg-primary text-white text center"),
    ],
    fluid=True,
)

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


Customizing the Yada image


Use the following props to change the icon and the hover message:

  • yada_src (string; optional): Location src of the image that you want to display for yada.

  • hover_message_dict (dict; optional): Props to display for the message when yada is not clicked and not playing a script. If not defined, the default name is "yada". Set name to "" to not display a header. Set message to "" to not display a greeting {name (string; optional), greeting (string; optional), style (dict; optional}

  • Set the position and size with CSS:

The default CSS for the Yada image when the app starts is:

.yada.sleeping {
    right: 30px;
    top: 5px;
    height: 50px;
    width: 35px;
}

yada_custom_icon

yada_icon = "https://user-images.githubusercontent.com/72614349/236646464-1471e596-b234-490d-bf84-e2ef7a63b233.png"
hover_message_dict = {
    "name": "Hedwig",
    "greeting": "Let's explore! Just pick a tour and we'll get started",
    "style": {"backgroundColor": "lightgreen"}
}

yada = YadaAIO(yada_id="my_yada", yada_src=yada_icon, hover_message_dict=hover_message_dict)


Adding scripts


You can add one or more scripts for the user to select the tour.

Yada navigates by CSS selector, so it can go to any element on a page. Learn more about selectors at Mozilla web-docs For example you could use a component's id like this: "#component_id". You can use a class selector like this: ".close-btn"

  • scripts (dict of list of dicts; optional): Dictionary of keys to scripts:
    • each key will have an array of: {target (string; required), convo (string; required), action (string; optional), action_args (string; optional)}

Here is a simple example of one script with one step. You can find more script examples in the demo app: yada_scripts.py file

yada_quickstart_script

import dash
from dash import html
import dash_bootstrap_components as dbc
from dash_yada import YadaAIO

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

yada = YadaAIO(
    yada_id="yada",
    scripts={
        "Intro": [
            {
                "target": "#title",
                "convo": "Welcome to My Dashboard tour!",
            },
        ]
    },
)

app.layout = dbc.Container(
    [
        yada,
        html.H4(
            "My Dashboard",
            className="p-3 bg-primary text-white text center",
            id="title",
        ),
    ],
    fluid=True,
)

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


Styling the tour steps


The steps in the script are displayed in a dbc.Offcanvas component. You can change the style using the steps_offcanvas_style prop. Note that in the scripts prop you can also use Markdown in the convo

import dash
from dash import html
import dash_bootstrap_components as dbc
from dash_yada import YadaAIO

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


steps_offcanvas_style = {
    "boxShadow": "0 4px 8px 0 rgba(0, 0, 0, 0.2), 0 6px 20px 0 rgba(0, 0, 0, 0.19)",
    "margin": "8px auto",
    "padding": "0px 24px 5px",
    "backgroundColor": "var(--bs-gray-500)",
    "color": "white",
    "borderRadius": 12,
    "maxWidth": 800,
}


yada = YadaAIO(
    yada_id="yada",
    steps_offcanvas_style=steps_offcanvas_style,
    scripts={
        "Intro": [
            {
                "target": "#title",
                "convo": """
                ### Welcome to My Dashboard tour!  
                The tour steps are are displayed in an offcanvas component and can be styled with the `steps_offcanvas_style` prop. 
                 
                Note that you can use Markdown in the "convo" prop.
                """,
            },
        ]
    },
)


app.layout = dbc.Container(
    [
        yada,
        html.H4(
            "My Dashboard",
            className="p-3 bg-primary text-white text center",
            id="title",
        ),
    ],
    fluid=True,
)

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