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, Number or Boolean.

<template>
  <el-radio v-model="radio" label="1">Option A</el-radio>
  <el-radio v-model="radio" label="2">Option B</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="radio" label="disabled">Option A</el-radio>
  <el-radio disabled v-model="radio" label="selected and disabled">Option B</el-radio>
</template>

<script>
  export default {
    data () {
      return {
        radio: '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="radio">
  <el-radio :label="3">Option A</el-radio>
  <el-radio :label="6">Option B</el-radio>
  <el-radio :label="9">Option C</el-radio>
</el-radio-group>

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

:::

Button style
