Multi-select Checkbox

[kvnn]

This adds a multi-select checkbox type , similar to Actions:

    options = [
        cl.CheckboxGroupOption(name='townhouse', value='townhouse', label='townhouse'),
        cl.CheckboxGroupOption(name='condo', value='condo', label='condo'),
        cl.CheckboxGroupOption(name='single_family', value='single_family', label='single_family'),
        cl.CheckboxGroupOption(name='multi_family', value='multi_family', label='multi_family'),
        cl.CheckboxGroupOption(name='land', value='land', label='land'),
        cl.CheckboxGroupOption(name='other', value='other', label='other')
    ]

    checkbox_group = cl.CheckboxGroup(
        name=current_model.__tablename__,
        options=options
    )

    res = await cl.AskCheckboxMessage(
        content=message,
        checkbox_group=checkbox_group
    ).send()
 
    if res:
        print(res['selected'])
        selected_names = [option['name'] for option in res['selected']]

This is interesting! Two feedback:

1. It would be nice to have a test for this (you can look at the AskAction test for instance)
2. The save button taking the whole width seems a bit too much. Maybe auto width and aligned to the right or left?
