Set value of checklist by label when options is given as list of dicts

Dash Python

Hi! So this works as expected and the first two options are selected by default:

app.layout = html.Div([dcc.Checklist(
        id='checklist',
        options={str(i): f'{10 + i}' for i in range(5)},
        value=['0', '1'],
)

In this example, however, nothing is selected by default:

app.layout = html.Div([dcc.Checklist(
        id='checklist',
        options=[{'label': str(i), 'value': f'{10 + i}'} for i in range(5)],
        value=['0', '1'],
)

This works as well:

app.layout = html.Div([dcc.Checklist(
        id='checklist',
        options=[{'label': str(i), 'value': f'{10 + i}'} for i in range(5)],
        value=['10', '11'],
)

But I would like to use the labels instead.

By the way, this also doesn’t work (returns errors):

app.layout = html.Div([dcc.Checklist(
        id='checklist',
        options=[{'label': str(i), 'value': f'{10 + i}'} for i in range(5)],
        value=[{'label': '10'}, {'label': '11'}],
)

Hi @lambdakappatheta
This piece of code won’t work because if the first label is selected its value is 10. So choosing the default values 0 or 1 won’t do anything because they don’t exist.
