This section explains how to create a simple RadioButton, and to configure its available functionalities in Vue using Vue quickstart seed repository.

Prerequisites

System requirements for Syncfusion Vue UI components

Dependencies

The following list of dependencies are required to use the RadioButton component in your application.

|-- @syncfusion/ej2-vue-buttons
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-buttons
    |-- @syncfusion/ej2-vue-base

Installation and configuration

You can use Vue CLI to setup your Vue applications.
To install Vue CLI use the following command.

npm install -g @vue/cli

npm install -g @vue/cli-init

Start a new project using below Vue CLI command.

vue init webpack-simple quickstart

cd quickstart

npm install

Install Syncfusion RadioButton packages using below command.

npm install @syncfusion/ej2-vue-buttons --save

Registering RadioButton component using Vue.use()

Import the RadioButton Plugin from the Essential JS 2 Vue package and register the same using Vue.use() with Component Plugin as its argument.

Refer to the code snippet given below.

import Vue from 'vue';
import { RadioButtonPlugin } from "@syncfusion/ej2-vue-buttons";

Vue.use(RadioButtonPlugin);

export default {}

By registering component plugin in Vue, all child directives are also globally registered. We can also use Vue.Component() to register RadioButton. Refer here to know more about component registration.

Initialize RadioButton

Add the EJ2 Vue RadioButton using <ejs-radiobutton> to the <template> section of the App.vue file in src directory.

<template>
<ejs-radiobutton label='Default'></ejs-radiobutton>
</template>

<script>
import Vue from 'vue';
import { RadioButtonPlugin } from "@syncfusion/ej2-vue-buttons";

Vue.use(RadioButtonPlugin);

export default {}
</script>

Adding CSS Reference

Add RadioButton component’s styles as given below in <style> section of the App.vue file.

<style>
@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-buttons/styles/material.css";
</style>

Run the application

Now run the npm run dev command in the console, it will build your application and open in the browser.

The following example shows a basic RadioButton component.

app.vue

<template>
<ul>
<li><ejs-radiobutton label='Option 1' name='default'></ejs-radiobutton></li>
<li><ejs-radiobutton label='Option 2' name='default' checked=true></ejs-radiobutton></li>
</ul>
</template>

<script>
import Vue from 'vue';
import { RadioButtonPlugin } from "@syncfusion/ej2-vue-buttons";
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);
Vue.use(RadioButtonPlugin);

export default {}
</script>

<style>
  @import "../node_modules/@syncfusion/ej2-base/styles/material.css";
  @import "../node_modules/@syncfusion/ej2-buttons/styles/material.css";

.e-radio-wrapper {
  margin-top: 18px;
}

li {
  list-style: none;
}
</style>

Change the RadioButton state

The Essential JS 2 RadioButton contains 2 states visually, they are as follows:

• Checked
• Unchecked

The RadioButton checked property is used to handle the checked and unchecked state. In the checked state an inner circle will be added to the visualization of RadioButton.

app.vue

<template>
<ul>
<li><ejs-radiobutton label='Option 1' name='default' checked=true></ejs-radiobutton></li>
<li><ejs-radiobutton label='Option 2' name='default'></ejs-radiobutton></li>
</ul>
</template>

<script>
import Vue from 'vue';
import { RadioButtonPlugin } from "@syncfusion/ej2-vue-buttons";
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);
Vue.use(RadioButtonPlugin);

export default {}
</script>

<style>
  @import "../node_modules/@syncfusion/ej2-base/styles/material.css";
  @import "../node_modules/@syncfusion/ej2-buttons/styles/material.css";

.e-radio-wrapper {
  margin-top: 18px;
}

li {
  list-style: none;
}
</style>
