Disallowed values

The disallowed values validator let's you ensure that a component doesn't have one of the specified values.

Example​

import React from "react";
import {
  createForm,
  pageBreak,
  textField,
  StatefulFormView,
  content,
  disallowedValues,
} from "@fab4m/fab4m";
import "@fab4m/fab4m/css/basic/basic.css";

const form = createForm({
  city: textField({
    label: "City",
    validators: [
      disallowedValues(
        ["Gothenburg", "Stockholm"],
        "Choose anything but Stockholm or Gothenburg"
      ),
    ],
    required: true,
  }),
  break: pageBreak(),
  content: content({}, () => <div>Great choice!</div>),
});

export default function TextFieldExample() {
  return <StatefulFormView form={form} hideSubmit={true} />;
}
