Public bug reported:

Horizon form supports the switchable/switched mechanism which allows to
show some field depending on another field.

When MultipleChoiceField is 'switched' field and the widget ThemableCheckboxSelectMultiple is used, the field is never hidden.
There is no such example in the horizon repo, but we have an example in neutron-vpnaas-dashboard [1].

'subnets' field ("Local System Subnets") should be shown only when
"subnet" is selected in 'type' field, but 'subnets' field is always
shown.

If I replace ThemableCheckboxSelectMultiple with CheckboxSelectMultiple
(Django default widget for MultipleChoiceField), the field is
hidden/shown conditionally as expected. Thus I believe it is a bug of
ThemableCheckboxSelectMultiple.
