ACV Radio

Radio button allows to select one option from a set. Used in cases where a list of two or more parameters is mutually exclusive, that is, the user can select only one parameter. Radio buttons should have one selected option by default.

Basic usage

Use component with component to display the label. Radio button value binds with v-model and value as the selected value.

Source code

<script setup>
  import AcvFormItem from '@/components/form-item/formItem.vue';
  import AcvRadio from '@/components/radio/radio.vue';
  import { ref } from 'vue';

  const picked = ref('apple');
</script>

<template>
  <AcvFormItem
    v-model="picked"
    :control="AcvRadio"
    label="🍎 Apple"
    value="apple"
  />
  <AcvFormItem
    v-model="picked"
    :control="AcvRadio"
    label="🍌 Banana"
    value="banana"
  />
  <AcvFormItem
    v-model="picked"
    :control="AcvRadio"
    label="🍇 Grape"

  />
  <AcvFormItem

    :control="AcvRadio"
