Subfields
I would like to have a "subfield" option for my membership fields. With that, a member who chooses a certain option of the field is given additional multiple choices. For example, a member who picks "music" can then pick from "piano", "guitar", "singing" and such. Sub-fields would help with a more logical organization of member profiles.

Under event registration we would like to be able to create registration field that if they click yes a specific set of fields must be answered and if they click no a different set of fields must be answered.

This is similar to other wishlist items regarding logic/rules/conditions so we can make smarter forms. WA's forms are currently all-or-nothing, so members have to scroll past things that don't pertain to them, e.g. "Child #6 Name", "Child #6 Age", "Child #6 Tshirt size".
Examples of desired functionality include:
"# of children in family?" -> "6" = opens 6 fields for names, ages, sizes.
"Are you 65 or older?" -> "yes" = applies senior discount
"Are you already a stockholder? -> "no" = opens stock purchasing options with extra charges attached
OR -> "yes" = opens field to enter stock number -

I would appreciate comments from other users who need this - and additional examples.
