refactor inputs into their own directory; restrict object picker type based on linkTo
make pages and images use the generic forms
scroll to field with validation error
report missing required fields in the context of the field
don't post null values
load defaultValue for add form from schema
include blank option for non-required enums
refactor fetched to pass component as a child node
