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

Prerequisites

System requirements for Syncfusion® Vue UI components

Setup 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 Drop down list component as an example. Install the @syncfusion/ej2-vue-dropdowns package by running the following command:

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

or

yarn add @syncfusion/ej2-vue-dropdowns

Import Syncfusion® CSS styles

Syncfusion® components require CSS stylesheets to display correctly. You can import themes in various ways, such as using CSS or SASS styles from npm packages, CDN, CRG, and Theme Studio. Refer to themes topic to learn more about built-in themes and different ways to reference themes in a Vue project.

In this article, the Material3 theme is applied using CSS styles, which are available in installed packages. The necessary Material3 CSS styles for the Dropdown list component and its dependents were imported into the <style> section of the src/App.vue file.

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

The order of CSS imports matters. Import base styles first, then component-specific styles. Missing CSS imports can result in misaligned layouts, buttons without styling, or missing visual elements in popups and dialogs.

Add Syncfusion® Vue component

Follow the below steps to add the Vue Dropdown list component:

1. First, import and register the Dropdown list component in the script section of the src/App.vue file.

<script setup>
import { DropDownListComponent as EjsDropdownlist } from "@syncfusion/ej2-vue-dropdowns";
</script>
<script>
import { DropDownListComponent } from "@syncfusion/ej2-vue-dropdowns";

export default {
  components: {
    'ejs-dropdownlist': DropDownListComponent
  }
}
</script>

2. In the template section, define the Drop down list component with the dataSource and placeholder property.

<template>
  <div id="app">
    <div id='container' style="margin:50px auto 0; width:250px;">
        <br>
        <ejs-dropdownlist id='Dropdownlist' :dataSource='sportsData' placeholder='Select a game'></ejs-dropdownlist>
    </div>
  </div>
</template>

Binding data source

After initialization, populate the Dropdown list with data using the dataSource  property. Here, an array of string values is passed to the Dropdown list component.

<template>
  <div id="app">
    <div id='container' style="margin:50px auto 0; width:250px;">
        <br>
        <ejs-dropdownlist id='Dropdownlist' :dataSource='sportsData' placeholder='Select a game'></ejs-dropdownlist>
    </div>
  </div>
</template>

<script setup>
import { DropDownListComponent as EjsDropdownlist } from "@syncfusion/ej2-vue-dropdowns";
const sportsData = ['Badminton', 'Cricket', 'Football', 'Golf', 'Tennis'];
</script>
<template>
  <div id="app">
    <div id='container' style="margin:50px auto 0; width:250px;">
        <br>
        <ejs-dropdownlist id='Dropdownlist' :dataSource='sportsData' placeholder='Select a game'></ejs-dropdownlist>
    </div>
  </div>
</template>
<script>
import { DropDownListComponent } from "@syncfusion/ej2-vue-dropdowns";
export default {
  components: {
    'ejs-dropdownlist': DropDownListComponent
  },
  data (){
    return {
      sportsData: ['Badminton', 'Cricket', 'Football', 'Golf', 'Tennis']
    }
  }
}

</script>

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

<template>
  <div id="app">
    <div id='container' style="margin:50px auto 0; width:250px;">
      <br>
      <ejs-dropdownlist id='dropdownlist' :dataSource='sportsData' placeholder='Select a game'></ejs-dropdownlist>
    </div>
  </div>
</template>
<script setup>
import { DropDownListComponent as EjsDropdownlist } from "@syncfusion/ej2-vue-dropdowns";

const sportsData = ['Badminton', 'Cricket', 'Football', 'Golf', 'Tennis'];
</script>
<style>
@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-inputs/styles/material.css";
@import "../node_modules/@syncfusion/ej2-vue-dropdowns/styles/material.css";
</style>
<template>
  <div id="app">
    <div id='container' style="margin:50px auto 0; width:250px;">
      <br>
      <ejs-dropdownlist id='dropdownlist' :dataSource='sportsData' placeholder='Select a game'></ejs-dropdownlist>
    </div>
  </div>
</template>
<script>
import { DropDownListComponent } from "@syncfusion/ej2-vue-dropdowns";

export default {
  name: "App",
  components: {
    'ejs-dropdownlist': DropDownListComponent
  },
  data() {
    return {
      sportsData: ['Badminton', 'Cricket', 'Football', 'Golf', 'Tennis']
    }
  }
}

</script>
<style>
@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-inputs/styles/material.css";
@import "../node_modules/@syncfusion/ej2-vue-dropdowns/styles/material.css";
</style>

Run the project

To run the project, use the following command:

npm run serve

or

yarn run serve

Configure the Popup List

By default, the width of the popup list automatically adjusts according to the Dropdown list input element’s width, and the height of the popup list has ‘300px’.

The height and width of the popup list can also be customized using the popupHeight  and popupWidth properties respectively

<template>
  <div id="app">
    <div id='container' style="margin:50px auto 0; width:250px;">
      <br>
      <ejs-dropdownlist id='dropdownlist' popupHeight="200px" popupWidth="250px" :dataSource='sportsData'
        placeholder='Select a game'></ejs-dropdownlist>
    </div>
  </div>
</template>
<script setup>
import { DropDownListComponent as EjsDropdownlist } from "@syncfusion/ej2-vue-dropdowns";

const sportsData = ['Badminton', 'Cricket', 'Football', 'Golf', 'Tennis'];

</script>
<style>
@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-inputs/styles/material.css";
@import "../node_modules/@syncfusion/ej2-vue-dropdowns/styles/material.css";
</style>
<template>
  <div id="app">
    <div id='container' style="margin:50px auto 0; width:250px;">
      <br>
      <ejs-dropdownlist id='dropdownlist' popupHeight="200px" popupWidth="250px" :dataSource='sportsData'
        placeholder='Select a game'></ejs-dropdownlist>
    </div>
  </div>
</template>
<script>
import { DropDownListComponent } from "@syncfusion/ej2-vue-dropdowns";

export default {
  name: "App",
  components: {
    'ejs-dropdownlist': DropDownListComponent
  },
  data() {
    return {
      sportsData: ['Badminton', 'Cricket', 'Football', 'Golf', 'Tennis'];
    }
  }
}

</script>
<style>
@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-inputs/styles/material.css";
@import "../node_modules/@syncfusion/ej2-vue-dropdowns/styles/material.css";
</style>
