Is there a way to observe whether a checkbox in a container of checkboxes is checked and disable all the checkboxes in that container if so?

Question

I'm building an interface in Jupyter Notebook, and for one of the questions being asked (there is a VBox consisting of a Label with the value being the name of the question), users should only be able to select one of the choices. Since I am asking multiple questions, and some of the questions allow multiple answers, I am using a checkbox because I do not know how to make the vertical radio buttons have consistent spacing with the other checkboxes.

this image gives an idea of what the layout looks like.

Please provide enough code so others can better understand or reproduce the problem. — Community, Jul 28 '22 at 22:39

You could keep the checkboxes in a list and call a function every time any of those checkboxes are changed.

For example:

def onCheckBoxChanged(event):
    widget = event['owner']
    for checkbox in groupby_checkboxes:
        if checkbox != widget:
            checkbox.value = False

groupby_checkboxes = []
for i in range(4):
    new = widgets.Checkbox(value=False)
    new.observe(onCheckBoxChanged, names=['value'])

Is there a way to observe whether a checkbox in a container of checkboxes is checked and disable all the checkboxes in that container if so?
