BootStrap: Right aligning nested accordion

I have a nested accordion that looks like:

enter image description here

But I would like to right-align them so that all the collapse arrows are aligned. I am using Plotly Dash so my code looks like:

d = {'1': {'1.1': {'1.1.1': {}}, '1.2': {'1.2.1': {}}}, 
  '2': {'2.1': {'2.1.1': {}}, '2.2': {'2.2.2': {}}}}

def generate_accordion(input_dictionary):
    output = dbc.Accordion([], start_collapsed=True, always_open=True, flush=True)
    for key, subdict in input_dictionary.items():
        output.children.append(dbc.AccordionItem(generate_accordion(subdict), title=key, style={'display': 'block', 'left': '20px', 'text-align': 'center'}))
    return output
Accordion_Nest = generate_accordion(d)
print(Accordion_Nest)

app = Dash(__name__,
            external_stylesheets=[dbc.themes.BOOTSTRAP, 'https://codepen.io/chriddyp/pen/bWLwgP.css'],
            prevent_initial_callbacks=True
            )

app.layout = html.Div(
    [
        Accordion_Nest,
    ]
)

I hope this helps you out. I am not familiar with plotly dash but using Bootstrap 5 I was able to replicate your nested divs and set the padding-right: 0 for div.accordion-body which achieved aligning all the collapse arrows vertically.

Additionally, you could probably set each accordion-header and accordion-body divs to be w-100 if that is also something you are looking for.

I have a code snippet with my results below. Best of luck!

div.accordion-body{
  padding-right: 0 !important;
}
