Checklist with dictionary value

[mxlei01]

It seems that value with dictionary causes only one option to appear:

dcc.Checklist(
    id="account-ad-options",
    options=[
        {'label': 'Optimization', 'value': {"optimization": True}},
        {'label': 'Reports', 'value': {"reports": True}}
    ],
    values=[]
),

dcc.Checklist(
    id="account-ad-options",
    options=[
        {'label': 'Optimization', 'value': 'optimization'},
        {'label': 'Reports', 'value': 'reports'}
    ],
    values=[]
),

Dictionary as values could be pretty handy to control inputs going inside a function with ChainMap and passing the dictionary as variables into a function with ** (two star).

This isn't supported in our underlying component. Our documentation (https://dash.plot.ly/dash-core-components/dropdown) should do a better job of explaining these nested types but we also don't display any examples that use nested objects. We'll do a better job of raising errors for these types of issues when #264 is solved.

If you need to do this, create a separate dictionary:

values = {
     'optimization': {'key': 'value'}
}

dcc.Checklist(options=[{'label': 'Optimization', 'value': 'optimization'})

and refer to it in your callback:

more_data = values[value]  # {'key': 'value'}

Below code will help to enable all the options by defualt :

default_options = [
{'label': 'Optimization', 'value': 'optimization'},
{'label': 'Reports', 'value': 'reports'}
]
dcc.Checklist(
id="account-ad-options",
options=default_options ,
value=[d["value"] for d in default_options]
),
