Form with Field Groups for Ark UI

Personal Information and Address as two groups, with the names side by side and city beside ZIP code.

Personal Information puts first and last name on one row. Address puts the street on its own row, then city beside ZIP. ZIP must be a 5-digit or ZIP+4 code.

Use it when a longer form needs headings so people can scan it. One undivided stack is a plain Field group. In React, Ark UI does not group the fields. The sections do.

FAQ

How are the two groups separated?

Each group is a FieldSet with a FieldLegend (Personal Information, Address) and its own FieldGroup. The outer FieldGroup spaces the two sets and the button.

Which fields share a row?

First Name and Last Name, then City and ZIP Code, each pair in a div with grid grid-cols-2 gap-4. Street Address spans the full width.

What message does each field use?

First and last name need 2 characters ("First name must be at least 2 characters.", "Last name must be at least 2 characters."). Street and city are .min(2) with "Street address is required." and "City is required." ZIP shows "Please enter a valid ZIP code."

What ZIP does the regex accept?

zipCode matches ^\d{5}(-\d{4})?$: five digits, optionally a hyphen and four more, such as 10001 or 10001-1234. The pattern is a module-level constant.

What are the initial values?

defaultValues sets all five fields to empty strings.

When does Continue validate the groups?

Continue is a type="submit" button. mode is unset, so one schema checks both groups on submit, and onSubmit logs the five values once they all pass.
