Form with Multiple Selects for Ark UI

A name plus required country, timezone, and language selects, checked together before the settings save.

Name needs 2 characters. Country, timezone, and language each start on a placeholder and must be picked. Save Settings names the one you skipped.

Use it when several closed lists belong on one settings form. A single country is just a Select. In React, Ark UI does not know which select is required.

FAQ

What does each field check?

name is .min(2) with "Name must be at least 2 characters." country, timezone and language each start as "" and must pass .min(1), with "Please select a country.", "Please select a timezone." and "Please select a language."

How is each select wired?

The selects are one selects array mapped to a Controller each, with its label, placeholder and options. Each has a createListCollection; value is [field.value] and onValueChange stores value[0].

What values do the three lists use?

Country uses us, uk, ca and au. Timezone uses est, cst, mst and pst. Language uses en, es, fr and de. The form stores that value, not the visible label.

What shows before anything is picked?

All four values start as "", so the triggers show their placeholders: "Select country", "Select timezone" and "Select language". The Name input's placeholder is John Doe.

Which field has helper text?

Only Language, whose FieldDescription says "Choose your preferred language." The other fields show just their FieldError when they fail.

What does Save Settings submit?

Save Settings is a type="submit" button. form.handleSubmit(onSubmit) runs the schema and, once the name is long enough and all three selects have a value, logs { country, language, name, timezone } to the console.
