React js example. color picker

Preview Code

1. First, we need fresh reactjs setup, and for that, we need to run below commands into out terminal, and also we should have latest node version installed on our system:

npx create-react-app my-awesome-project

cd my-awesome-project

npm start

2. Now we need to run below commands into our project terminal to get bootstrap and related modules into our reactjs application:

npm install [email protected] --save

npm start //For start project again

3. Finally for the main output, we need to add below code into our my-awesome-project/src/App.js file or if you have fresh setup then you can replace my-awesome-project/src/App.js file code with below code:

import React from 'react';
import './App.css';
import 'bootstrap/dist/css/bootstrap.min.css';


function App() {
  
	return (
		<div>
			<div class="container">
    <div class="row">
        <div class='col-md-6'>
        <div class="form-group">
            <label for="" class="">Select Colour</label>
                <div class="dropdown">
                            <button class="btn _select_color dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Green<span class="caret _right"></span>
                            <span _text_display="Green" class="color green"></span></button>
                            <ul class="dropdown-menu _select_color_drop" aria-labelledby="dropdownMenu1">
                                <li><span _text_display="Green" class="color green"></span></li>
                                <li><span _text_display="Red" class="color red"></span></li>
                                <li><span _text_display="Yellow" class="color yellow"></span></li>
                                <li><span _text_display="Brown" class="color brown"></span></li>
                                <li><span _text_display="Orange" class="color orange"></span></li>
                                <li><span _text_display="Pink" class="color pink"></span></li>
                                <li><span _text_display="Silver" class="color silver"></span></li>
                                <li><span _text_display="Bule" class="color blue"></span></li>
                                <li><span _text_display="TEAL" class="color TEAL"></span></li>
                                <li><span _text_display="NAVY" class="color NAVY"></span></li>
                                <li><span _text_display="PURPLE" class="color PURPLE"></span></li>
                                <li><span _text_display="OLIVE" class="color OLIVE"></span></li>
                                <li><span _text_display="LIME" class="color LIME"></span></li>
                            <input type="hidden" name="_color" value="Green"/></ul>
                        </div>
                    </div>
        </div>
    </div>
</div>

		</div>
	);
}
export default App;

4. Now we need to add below code into our my-awesome-project/src/App.css file :
