607	Admin option to show/hide fields	Wilson Miner	nobody	"'''Concept:''' An admin option that specifies a list of fields to show/hide based on the value of another field.

'''Example:''' An ""I like cake"" checkbox that, when checked, shows two previously hidden text fields ""Favorite cake"" and ""Favorite frosting"".

'''Code Example:''' 

{{{ 
admin.switch = [('likes_cake', {'True': ['favorite_cake', 'favorite_frosting']})]
}}}

You could also tie this to a particular value of a select field:

{{{ 
admin.switch = [('gender', {'M': ['favorite_sport'], 'F': ['favorite_soap_opera']})]
}}}

'''Unsolved issues:'''

 * Need some place to specify the initial state of the targeted fields (visible or hidden). Default (and most common case) would be hidden, but there are cases where this needs to be reversed.
 * All hiding and should happen in javascript, so fields don't get hidden that can't be turned back on with javascript disabled. The switch option could also tie into the validation framework so unnecessary fields (meant to be hidden) don't get filled in even when javascript is off.
 * Any other ideas?"	enhancement	closed	contrib.admin		normal	wontfix			Accepted	0	0	0	0	0	0
