Field

A labeled form field wrapper for composing inputs and validation UI.

Usage

ui.field({
  label: "Name",
  required: true,
  error: state.nameError,
  hint: "Your display name",
  children: ui.input({
    id: "name",
    value: state.name,
    onInput: (value) => app.update((s) => ({ ...s, name: value })),
  }),
})

With useForm, you can generate the same structure in one call:

form.field("name", { label: "Name", required: true, hint: "Your display name" })

Props

Notes

• The wrapped child remains the focusable element.
• Field renders at most one footer line. A non-empty error takes precedence; otherwise hint is shown.
• An empty-string error is treated as absent, so hint still renders when provided.
• Footer colors come from the active theme. The exported field style helpers are structural presets, not fixed color tokens.
• Use Field to keep label, hint, and error layout consistent across forms.
