import dash_html_components as html

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

sidebar = html.Div(
    dbc.Nav(
        [
            dbc.NavItem(dbc.NavLink(html.I(className="fa fa-home"), href="/")),
            dbc.NavItem(dbc.NavLink(html.I(className="fa fa-user"), href="/profile")),
            dbc.NavItem(dbc.NavLink(html.I(className="fa fa-cog"), href="/settings")),
        ],
        vertical=True,
        pills=True
    ),
    className="sidebar"
)

app.layout = html.Div(
    [
        sidebar,
        # 其他内容
    ]
)

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