  2. Install the React-Select and Bootstrap packages
  3. Create Select Box Dropdown Component
  4. Adding Select Component
  5. Properties and Configurations in React-Select

Create React Application

To begin with, let’s create a new React application executing the below npx command in the CLI terminal.

$ npx create-react-app react-bootstrap-modal

Move into the application directory

$ cd react-bootstrap-modal

 

Install the React-Select and Bootstrap packages

After the application is created, next we will install the profound react-selectlibrary package. We also need to install the bootstrap as a dependency package.

Execute the following command in the CLI terminal to install the library.

$ npm install react-select bootstrap --save

 

Create Select Box Dropdown Component

Next, we will create a new Component in our React app; The component will have events and methods to handle data;  render Select template.

Our component we have single and multi-select components. A react-select component is created by adding the <Select/> with  options props to it.

Three types of Select components we have; Single selection select box; Multiple selection with tags; Filter or search option in the select box.

Under the src folder create selectDropdownComponent.js file and update with the following code.

import React from "react";

import Select from "react-select";

const icecreams = [
    { value: 'chocolate', label: 'Chocolate' },
    { value: 'strawberry', label: 'Strawberry' },
    { value: 'vanilla', label: 'Vanilla' },
  ];;

class SelectDropDownComponent extends React.Component {
  state = {
    selectedOption: null,
  };
  handleChange = (selectedOption) => {
    this.setState({ selectedOption });
    console.log(`Option selected:`, selectedOption);
  };

  render() {
    const { selectedOption } = this.state;

    return (
      <div className="container">
        <div className="row">
          <div className="col-md-12">

            <h5>Single SelectBox</h5>
            <Select
              value={selectedOption}
              onChange={this.handleChange}
              options={icecreams}
            />

          </div>
        </div>
        <div className="row">
          <div className="col-md-12">

            <h5>Multiple SelectBox</h5>
            <Select
              value={selectedOption}
              isMulti="true"
              onChange={this.handleChange}
              options={icecreams}
            />

          </div>
        </div>
        <div className="row">
          <div className="col-md-12">

            <h5>Multiple SelectBox with Search</h5>
            <Select
              value={selectedOption}
              isMulti="true"
              isSearchable="true"
              onChange={this.handleChange}
              options={icecreams}
            />

          </div>
        </div>
      </div>
    );
  }
}

export default SelectDropDownComponent;

 

Adding Select Component

To use the SelectDropDownComponent in our react app, open the App.js main component then update with the following code.

import './App.css';
import '../node_modules/bootstrap/dist/css/bootstrap.min.css';
import SelectDropDownComponent from './selectDropdownComponent'

function App() {
  return (
    <div className="App">
       <SelectDropDownComponent />
    </div>
  );
}

export default App;

Above, we have also imported the bootstrap.css file from the bootstrap package we installed.

 

Properties and Configurations in React-Select

We already used the event handlers and few other important properties to enable Multiselect and enable search filter option. Let’s have a look at other useful properties available for the React-Select component.

  • autoFocus – focus the control when it mounts
  • className – apply a className to the control
  • classNamePrefix – apply classNames to inner elements with the given prefix
  • isDisabled – disable the control
  • isMulti – allow the user to select multiple values
  • isSearchable – allow the user to search for matching options
  • name – generate an HTML input with this name, containing the current value
  • onChange – subscribe to change events
  • options – specify the options the user can select from
  • placeholder – change the text displayed when no option is selected
  • value – control the current value

 

How to Customise UI Style of React-Select Component?

Customization of UI style of  React-Select is fairly easy, it gives more flexibility in enhancing the user experience of the application.

The styles prop can be used to provide custom styling to the component as shown below.

import React from "react";

import Select from "react-select";

const icecreams = [
    { value: 'chocolate', label: 'Chocolate' },
    { value: 'strawberry', label: 'Strawberry' },
    { value: 'vanilla', label: 'Vanilla' },
  ];

  const colourStyles = {
    control: styles => ({ ...styles, backgroundColor: 'white' }),
    option: (styles, { data, isDisabled, isFocused, isSelected }) => {
      return {
        ...styles,
        backgroundColor: isDisabled
          ? null
          : isSelected
          ? data.color
          : isFocused
          ? 'red'
          : null,
        color: isDisabled
          ? '#ccc'
          : isSelected
          ? 'white'
            ? 'white'
            : 'black'
          : data.color,
        cursor: isDisabled ? 'not-allowed' : 'default',
  
        ':active': {
          ...styles[':active'],
          backgroundColor:
            !isDisabled && (isSelected ? data.color : 'green'),
        },
      };
    }
};  

class SelectDropDownComponent extends React.Component {
  state = {
    selectedOption: null,
  };
  handleChange = (selectedOption) => {
    this.setState({ selectedOption });
    console.log(`Option selected:`, selectedOption);
  };

  render() {
    const { selectedOption } = this.state;

    return (
      <div className="container">
        <div className="row">
          <div className="col-md-12">

            <h5>Single SelectBox</h5>
            <Select
              value={selectedOption}
              onChange={this.handleChange}
              options={icecreams}
            />

          </div>
        </div>
        <div className="row">
          <div className="col-md-12">

            <h5>Multiple SelectBox</h5>
            <Select
              value={selectedOption}
              isMulti="true"
              onChange={this.handleChange}
              options={icecreams}
              styles={colourStyles}
            />

          </div>
        </div>
        <div className="row">
          <div className="col-md-12">

            <h5>Multiple SelectBox with Search</h5>
            <Select
              value={selectedOption}
              isMulti="true"
              isSearchable="true"
              onChange={this.handleChange}
              options={icecreams}
            />

          </div>
        </div>
      </div>
    );
  }
}
