I need a WordPress form plugin that meets these requirements (at a minimum).
1. Form fields can be styled as to font color, size and face & decoration. I'm talking the field the submitter enters data into, not the captions. Hopefully, captions can be styled too.
2. Calendar form fields with calendar "picker".
3. Custom editing available. For example, customers served ONLY in Ohio, zip code must be in Ohio; email address reasonableness test (must contain @ sign & .).
4. Ability to accept only numeric input into field.
5. Normal <select> type pulldowns.
6. Free or low cost.
