I seem to recall this might have been answered before but can't find it?
In a plugin's devices.xml, I have a group of fields whose visibility is enabled if checkbox A field is enabled. So far so good.
In the group of fields that are now visible, I want the fields in this group to be hidden or visible dependant on another checkbox B. However regardless of the setting of this check box B, the fields should not be visible if the checkbox A field is not enabled.
Is this possible as I haven't been able to get my thoughts around how this could be achieved.
