A lot has been said about this in this forum. I thought I'd open a new thread to combine all feature requests concerning customizing advanced fields. I'd personally like to customize the Address field and the Name field as follows:
Name field:
- Firstname (e.g. Rafael) | Preposition (e.g. van der) | Last name (e.g. Vaart)
Address field:
- Street | House number | House number suffix
- Postal code | City
Adding custom formats for advanced fields using hooks would be a very cool feature.
Another wish I have is to have more intelligent validation for advanced fields. For example I want Street to be required, but State to be optional. This is impossible right now.
