I am trying to create an image slider for my Dash app, but I get the following error: TypeError - TypeError: can only concatenate str (not "list") to str
I looked through my code to see if any of the children are not wrapped up properly but they looked good, or maybe I am missing something? What could I be possibly be doing wrong?
Here is code below:
import os
import dash
import dash_core_components as dcc
import dash_html_components as html
import dash_bootstrap_components as dbc
from dash.dependencies import Input, Output, State
app = dash.Dash(__name__,
external_stylesheets = dbc.themes.BOOTSTRAP)
#app = dash.Dash(__name__,
#external_stylesheets=[dbc.themes.BOOTSTRAP])
slider = html.Div(className = "hero-slider",
children = [
html.Div(className = "owl-hero-slider owl-carousel owl-theme",
children = [
html.Div(className = "item",
children = [
html.Div(className = "hero-image",
style = {
"background-image": "url(assets/img/slide-2.jpg)"
}),
html.Div(className = "hero-slider-content",
children = [
html.Div(className = "container",
children = [
html.Div(className = "row",
children = [
html.Div(className = "upSection animated slideOutUp",
children = [
html.Div("great", className = "text-top"),
html.Div("testing1", className = "text-mid"),
html.Div("why", className = "slider-line")
]),
html.Div(className = "downSection animated slideOutDown",
children = [
html.Div("build test", className = "text-bottom"),
html.A(className = "home-move-button", href = "#"),
])
])
])
])
]),
html.Div(className = "item",
children = [
html.Div(className = "hero-image",
style = {
"background-image": "url(assets/img/slide-1.jpg)"
}),
html.Div(className = "hero-slider-content",
children = [
html.Div(className = "container",
children = [html.Div(className = "row",
children = [
html.Div(className = "upSection animated slideOutUp",
children = [
html.Div("Second slider 2", className = "text-top"),
html.Div("We are just testing", className = "text-mid"),
html.Div("Yeah we go", className = "slider-line")
]),
html.Div(className = "downSection animated slideOutDown",
children = [
html.Div("build test", className = "text-bottom"),
html.A(className = "home-move-button", href = "#"),
])
])
])
])
]),
])
])
app.layout = html.Div(

children= slider,
