Getting Started with the KendoReact Dropdowns

This guide provides essential information about using the KendoReact Dropdowns package—you will learn how to install the package, add Dropdowns to your project, style the components, and activate your license. The steps demonstrated in this guide are applicable to all KendoReact Dropdowns.

The Dropdowns are part of KendoReact, a professional grade UI library with 110+ components for building modern and feature-rich applications. To try it out sign up for a free 30-day trial.Start Free Trial

Setting Up Your React Project

Before you install the KendoReact Dropdowns, make sure that you have a running React project. The easiest way to set up a React project is to use the Create React App approach that is described in the Get Started with KendoReact article.

Installing the Components

All KendoReact packages are distributed through npm and offer a similar installation experience. To use any of the Dropdowns, start with the installation of the npm package and its dependencies. Use Node.js v5.0.0 or later.

Navigate to the root folder of your React project and run the following command:

npm install --save @progress/kendo-react-dropdowns @progress/kendo-react-treeview @progress/kendo-react-buttons @progress/kendo-react-intl @progress/kendo-licensing @progress/kendo-svg-icons @progress/kendo-react-progressbars

Importing the Components

After installing the Dropdowns package, import the desired components in the React App. This guide shows how to add the DropDownList.

In the App component file of your React project (for example, src/App.js), add the following code:

jsx

// ES2015 module syntax
import { DropDownList } from '@progress/kendo-react-dropdowns';

jsx

// CommonJS format
const { DropDownList } = require('@progress/kendo-react-dropdowns');

If your project requires more Dropdowns, you can import them too. The Dropdowns package provides the following components:

AutoComplete
ComboBox
DropDownList
DropDownTree
MultiColumnComboBox
MultiSelect
MultiSelectTree

Using the Components

Get the data for the DropDownList.

const sizes = ['X-Small', 'Small', 'Medium', 'Large', 'X-Large', '2X-Large'];

Bind the data to the DropDownList and add the DropDownList's tags to the App component file of your React project (for example, src/App.js).

return (
    <div>
        <div>T-shirt size:</div>
        <DropDownList style={{ width: '300px' }} data={sizes} />
    </div>
);

To style the DropDownList, install and import the Default theme, which is one of the three beautiful themes for KendoReact.

3.1. Install the Default theme package.
sh
```
npm install --save @progress/kendo-theme-default
```
3.2. Import the CSS file from the package in src/App.js. Add this import before your existing App.css import.
jsx
```
import '@progress/kendo-theme-default/dist/all.css';
```
Build and run the application by typing the following command in the root folder of your project:
sh
```
npm start
```
Navigate to http://localhost:3000 to see the KendoReact DropDownList component on the page.

Now try to add another component from the Dropdowns package yourself. The procedures for installing, importing, and using the Dropdowns components are identical for all components in the package.

Activating Your License Key

Using any of the UI components in the KendoReact library requires either a commercial license key or an active trial license key.

Follow the instructions on the KendoReact My License page to activate your trial or commercial license. You can skip this step if your application already contains a KendoReact license file.
