Description of the issue: The checkboxes on the currently EN Form operate
independently of each other. There are times when this would be OK, but for
the GPI Opt-in this is not the correct behaviour. To see the correct
behaviour please have a look at any one of our EN Petitions:
https://act.greenpeace.org/page/47854/petition/1
The dependencies do not necessarily require the same hide/reveal behaviour
(b/c this I'm reliably told is actually poor UX) so it can simply be greyed
out. wmorrisj

Tasks

• In the Engaging Networks form editor add a Dependency field for checkboxes field type ONLY (see screenshot "checbox_editwindow.png")
• The dependency field text should be: "Only enable if following field is checked: " + dropdown showing all checkboxes field names
• If dependency field is filled in, then it will follow condition: enable [checkbox2] only if [checkbox1] is ticked
• If dependency field is filled in, then the dependent checkbox will be shown greyed out as in Will's design attached, until condition is met.
• Make sure reverse behaviour is tested and working
