Setting Up Your Vue Project

Before you install the Kendo UI for Vue Native ListBox, make sure that you have a running Vue project. The easiest way to set up a Vue project is to use the approach described in the Set up the Vue project section of the First Steps with JavaScript article.

Installing the ListBox Package

All Kendo UI for Vue Native packages are distributed through npm and offer a similar installation experience. To use the ListBox component, start with the installation of the ListBox npm package and its dependencies. Use Node.js v5.0.0 or later.

npm install --save @progress/kendo-vue-listbox @progress/kendo-licensing @progress/kendo-svg-icons

Importing the Component

After installing the package, import the ListBox component in the Vue App. To provide a flawless data transfer between multiple ListBox components, import the processListBoxData method.

In the src/App.vue file of your Vue project, import the ListBox component from the ListBox package.

jsx

// ES2015 module syntax
import { ListBox } from "@progress/kendo-vue-listbox";

jsx

// CommonJS format
const { ListBox } = require('@progress/kendo-vue-listbox');

Using the Component

Import the data file in the src/App.vue file.
jsx
```
  import { data } from './data';
```

Define the variables that will hold the data for the two ListBox components.

jsx

  data() {
    return {
      employees: data,
      developers: [],
    };
  }

Set the selectField value. That value will determine which items are selected.

jsx

  const SELECTED_FIELD = 'selected';
  .....
  data() {
    return {
      SELECTED_FIELD,
      ......
    };
  }

Add a handler for the onItemClick event of the ListBox. It is needed select or deselect items.

jsx

  handleItemClick(event, data, connectedData) {
    this[data] = this[data].map((item) => {
      if (item.name === event.dataItem.name) {
        item[SELECTED_FIELD] = !item[SELECTED_FIELD];
      } else if (!event.ctrlKey) {
        item[SELECTED_FIELD] = false;
      }
      return item;
    });
    this[connectedData] = this[connectedData].map((item) => {
      item[SELECTED_FIELD] = false;
      return item;
    });
  }

Add a handler for the onToolClick event of the ListBoxToolbar. It is needed to update the lists.

jsx

  handleToolBarClick(e) {
    let toolName = e.toolName || '';
    let result = processListBoxData(
      this.employees,
      this.developers,
      toolName,
      SELECTED_FIELD
    );

    this.employees = result.listBoxOneData;
    this.developers = result.listBoxTwoData;
  }

Add the markup of the two components to the template section of the src/App.vue file in your project.

jsx

<div class="container">
    <div class="row justify-content-center">
    <div class="col">
        <h6>Employees</h6>
        <ListBox
        :style="{ height: '400px', width: '100%' }"
        :dataItems="employees"
        :text-field="'name'"
        :selectedField="SELECTED_FIELD"
        :draggable="false"
        @itemclick="itemClick"
        :toolbar="'toolbar'"
        >
        <template v-slot:toolbar>
            <ListBoxToolbar
            :tools="[
                'moveUp',
                'moveDown',
                'transferTo',
                'transferFrom',
                'transferAllTo',
                'transferAllFrom',
                'remove',
            ]"
            :dataItems="employees"
            :dataConnected="developers"
            @toolclick="handleToolBarClick"
            />
        </template>
        </ListBox>
    </div>
    <div class="col">
        <h6>Developers</h6>
        <ListBox
        :style="{ height: '400px', width: '100%' }"
        :dataItems="developers"
        :textField="'name'"
        :selectedField="SELECTED_FIELD"
        @itemclick="itemClick2"
        />
    </div>
    </div>
</div>

To style the ListBox, install and import the Default theme, which is one of the four beautiful themes for Kendo UI for Vue.
1. Install the Default theme package.
  sh
```
npm install --save @progress/kendo-theme-default
```
2. Import the Theme package in src/App.vue..
  jsx
```
import '@progress/kendo-theme-default';
```
Build, run and test the application by typing the following command in the root folder of your project:
sh
```
npm run dev
```

Activating Your License Key
