Radio

Single selection among multiple options.

Basic usage

Radio should not have too many options. Otherwise, use the Select component instead.

:::demo Creating a radio component is easy, you just need to bind a variable to Radio's v-model. It equals to the value of label of the chosen radio. The type of label is String or Number.

<template>
  <el-radio class="radio" v-model="radio" label="1">optionA</el-radio>
  <el-radio class="radio" v-model="radio" label="2">optionB</el-radio>
</template>

<script>
  export default {
    data () {
      return {
        radio: '1'
      };
    }
  }
</script>

:::

Disabled

disabled attribute is used to disable the radio.

:::demo You just need to add the disabled attribute.

<template>
  <el-radio disabled v-model="radio1" label="disabled">optionA</el-radio>
  <el-radio disabled v-model="radio1" label="selected and disabled">optionB</el-radio>
</template>

<script>
  export default {
    data () {
      return {
        radio1: 'selected and disabled'
      };
    }
  }
</script>

:::

Radio button group

Suitable for choosing from some mutually exclusive options.

:::demo Combine <el-radio-group> with <el-radio> to display a radio group. Bind a variable with v-model of <el-radio-group> element and set label value in <el-radio>. It also provides change event with the current value as its parameter.

<el-radio-group v-model="radio2">
  <el-radio :label="3">optionA</el-radio>
  <el-radio :label="6">optionB</el-radio>
  <el-radio :label="9">optionC</el-radio>
</el-radio-group>

<script>
  export default {
    data () {
      return {
        radio2: 3
      };
    }
  }
</script>

:::

Button style

Radio with button styles.

:::demo You just need to change <el-radio> element into <el-radio-button> element. We also provide size attribute for these buttons: large and small.

<el-radio-group v-model="radio3">
  <el-radio-button label="New York"></el-radio-button>
  <el-radio-button label="Washington"></el-radio-button>
  <el-radio-button label="Los Angeles" :disabled="true"></el-radio-button>
  <el-radio-button label="Chicago"></el-radio-button>
</el-radio-group>

<script>
  export default {
    data () {
      return {
        radio3: ''
      };
