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

Prerequisites

System requirements for Syncfusion® Vue UI components

Dependencies

The list of dependencies required to use the DropDownButton component in your application is given as follows:

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

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

or

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 Dropdown Button component as an example. Install the @syncfusion/ej2-vue-splitbuttons package by running the following command:

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

or

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 Dropdown Button component and its dependents were imported into the <style> section of src/App.vue file.

<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 Dropdown Button component using Composition API or Options API:

1. First, import and register the Dropdown Button 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.

<script setup>
import { DropDownButtonComponent as EjsDropdownbutton } from "@syncfusion/ej2-vue-splitbuttons";
</script>
<script>
import { DropDownButtonComponent } from "@syncfusion/ej2-vue-splitbuttons";
export default {
    components: {
        'ejs-dropdownbutton': DropDownButtonComponent
    }
}
</script>

2. In the template section, define the Dropdown Button component with the content property.

<template>
<ejs-dropdownbutton :items='items'>Clipboard</ejs-dropdownbutton>
</template>

3. Declare the value for the items property in the script section.

<script setup>
const items = [
            {
                text: 'Cut'
            },
            {
                text: 'Copy'
            },
            {
                text: 'Paste'
            }];
</script>
<script>
data () {
        return {
            items:[
            {
                text: 'Cut'
            },
            {
                text: 'Copy'
            },
            {
                text: 'Paste'
            }]
        };
    }
</script>

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

<template>
    <ejs-dropdownbutton :items='items'>Clipboard</ejs-dropdownbutton>
</template>

<script setup>
import { DropDownButtonComponent as EjsDropdownbutton } from "@syncfusion/ej2-vue-splitbuttons";
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);
const items = [
    {
        text: 'Cut'
    },
    {
        text: 'Copy'
    },
    {
        text: 'Paste'
    }]
</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';
</style>
<template>
    <ejs-dropdownbutton :items='items'>Clipboard</ejs-dropdownbutton>
</template>

<script>
import { DropDownButtonComponent } from "@syncfusion/ej2-vue-splitbuttons";
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

export default {
    name: "App",
    components: {
        'ejs-dropdownbutton': DropDownButtonComponent
    },
    data() {
        return {
            items: [
                {
                    text: 'Cut'
                },
                {
                    text: 'Copy'
                },
                {
                    text: 'Paste'
                }]
        };
    }
}
</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';
</style>

Run the project

To run the project, use the following command:

npm run serve

or
