25 Apr 20258 minutes to read

This article provides a step-by-step guide for setting up a Vue 2 project using Vue-CLI and integrating the Syncfusion^® Vue Button group component using the Composition API / Options API.

Prerequisites

System requirements for Syncfusion^® Vue UI components

Dependencies

The list of dependencies required to use the Button component in your application is given below:

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

Setting up the Vue 2 project

To generate a Vue 2 project using Vue-CLI, use the vue create command. Follow these steps to install Vue CLI and create a new project:

npm install -g @vue/cli
vue create quickstart
cd quickstart
npm run serve

yarn global add @vue/cli
vue create quickstart
cd quickstart
yarn run serve

When creating a new project, choose the option Default ([Vue 2] babel, eslint) from the menu.

Vue 2 project

Once the quickstart project is set up with default settings, proceed to add Syncfusion^® components to the project.

Add Syncfusion^® Vue packages

Syncfusion^® packages are available at npmjs.com. To use Vue components, install the required npm package.

This article uses the Vue Button group component as an example. Install the @syncfusion/ej2-splitbuttons package by running the following command:

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

yarn add @syncfusion/ej2-vue-splitbuttons

Import Syncfusion^® CSS styles

You can import themes for the Syncfusion^® Vue component in various ways, such as using CSS or SASS styles from npm packages, CDN, CRG and Theme Studio. Refer to themes topic to know more about built-in themes and different ways to refer to themes in a Vue project.

In this article, the Material theme is applied using CSS styles, which are available in installed packages. The necessary Material CSS styles for the Button group component and its dependents were imported into the <style> section of src/App.vue file.

~/src/App.vue
<style>
@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-buttons/styles/material.css";
@import "../node_modules/@syncfusion/ej2-popups/styles/material.css";
@import "../node_modules/@syncfusion/ej2-splitbuttons/styles/material.css";
</style>

Add Syncfusion^® Vue component

Follow the below steps to add the Vue Button group component using Composition API or Options API:

1. First, import and register the Button group component in the script section of the src/App.vue file. If you are using the Composition API, you should add the setup attribute to the script tag to indicate that Vue will be using the Composition API.

Composition API (~/src/App.vue)
Options API (~/src/App.vue)
<script setup>
import { ButtonComponent as EjsButton } from '@syncfusion/ej2-vue-buttons';
</script>
<script>
import { ButtonComponent } from '@syncfusion/ej2-vue-buttons';

export default {
  components: {
    'ejs-button': ButtonComponent
  }
}
</script>

Creating Vue Sample

Add a div element with class name as e-btn-group and add the button elements that needs to be group inside the div element in App.vue file.

To render button elements as EJ2 Vue Button, then add Button dependencies in systemjs.config.js file. Then import ButtonPlugin from ej2-vue-buttons.

~/src/App.vue
<template>
  <div id='app'>
    <div class="e-btn-group">
        <ejs-button>HTML</ejs-button>
        <ejs-button>CSS</ejs-button>
        <ejs-button>Javascript</ejs-button>
    </div>
  </div>
</template>

Here is the summarized code for the above steps in the src/App.vue file:

Composition API (~/src/App.vue)
Options API (~/src/App.vue)
<template>
  <div id='app'>
    <div class="e-btn-group">
        <ejs-button>HTML</ejs-button>
        <ejs-button>CSS</ejs-button>
        <ejs-button>Javascript</ejs-button>
    </div>
  </div>
</template>
<script setup>
import { ButtonComponent as EjsButton } from '@syncfusion/ej2-vue-buttons';
</script>
<style>
@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-buttons/styles/material.css";
@import "../node_modules/@syncfusion/ej2-popups/styles/material.css";
@import "../node_modules/@syncfusion/ej2-splitbuttons/styles/material.css";
  #app {
   margin: 20px;
  }
  .e-btn-group {
    margin: 25px 5px 20px 20px;
  }
</style>
<template>
  <div id='app'>
    <div class="e-btn-group">
        <ejs-button>HTML</ejs-button>
        <ejs-button>CSS</ejs-button>
        <ejs-button>Javascript</ejs-button>
    </div>
  </div>
</template>
<script>
import { ButtonComponent } from '@syncfusion/ej2-vue-buttons';
export default {
  components: {
    'ejs-button': ButtonComponent
  },
  name: 'app'
}
</script>
<style>
@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-buttons/styles/material.css";
@import "../node_modules/@syncfusion/ej2-popups/styles/material.css";
@import "../node_modules/@syncfusion/ej2-splitbuttons/styles/material.css";
  #app {
   margin: 20px;
  }
  .e-btn-group {
    margin: 25px 5px 20px 20px;
  }
</style>

Run the project

To run the project, use the following command:

npm run serve

yarn run serve

Orientation

ButtonGroup can be arranged in vertical and horizontal orientation. By default, it is horizontally aligned.

Vertical Orientation

ButtonGroup can be aligned vertically using the built-in CSS class e-vertical to the target element.

The following example illustrates how to achieve vertical orientation in ButtonGroup,

Composition API (~/src/App.vue)
Options API (~/src/App.vue)
<template>
  <div id='app'>
    <div class="e-btn-group e-vertical">
        <ejs-button >HTML</ejs-button>
        <ejs-button >CSS</ejs-button>
        <ejs-button >Javascript</ejs-button>
    </div>
  </div>
</template>

<script setup>
import { ButtonComponent as EjsButton } from '@syncfusion/ej2-vue-buttons';
</script>

<style>
@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-buttons/styles/material.css";
@import "../node_modules/@syncfusion/ej2-popups/styles/material.css";
@import "../node_modules/@syncfusion/ej2-splitbuttons/styles/material.css";
  #app {
   margin: 20px;
  }
  .e-btn-group {
    margin: 25px 5px 20px 20px;
  }
</style>
<template>
  <div id='app'>
    <div class="e-btn-group e-vertical">
        <ejs-button >HTML</ejs-button>
        <ejs-button >CSS</ejs-button>
        <ejs-button >Javascript</ejs-button>
    </div>
  </div>
</template>
<script>
import { ButtonComponent } from '@syncfusion/ej2-vue-buttons';
export default {
  components: {
    'ejs-button': ButtonComponent
  },
  name: 'app'
}
</script>
<style>
@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-buttons/styles/material.css";
@import "../node_modules/@syncfusion/ej2-popups/styles/material.css";
@import "../node_modules/@syncfusion/ej2-splitbuttons/styles/material.css";
  #app {
   margin: 20px;
  }
  .e-btn-group {
    margin: 25px 5px 20px 20px;
  }
</style>

ButtonGroup with SplitButton component nesting won’t works in vertical orientation.
