javascript - Bootstrap Dropdown not working in React

Question

I'm trying to get a dropdown working inside a form for one of my React components. Here is how I'm setting up the dropdown portion of the code, the following is inside a form parent tag which is inside the div tag that I'm returning.:

//<div>
//<form>
//some code here

    <div className="row top-buffer">
        <div className="col">
            <div className="dropdown">
                <button 
                    className="btn btn-secondary dropdown-toggle" 
                    type="button" 
                    id="dropdownMenuButton" 
                    data-toggle="dropdown" 
                    aria-haspopup="true">
                    Dropdown
                </button>
                <div className="dropdown-menu" aria-labelledby="dropdownMenuButton">
                    <a className="dropdown-item" href="#nogo">Item 1</a>
                    <a className="dropdown-item" href="#nogo">Item 2</a>
                    <a className="dropdown-item" href="#nogo">Item 3</a>
                </div>
            </div>
        </div>
    </div>

//some code here
//</form>
//</div>

However, when I click the Dropdown button, it does not display the dropdown menu and the items in it.

All my other bootstrap components are working fine. What am I doing wrong?

EDIT:

I referenced bootstrap in my index.js:

import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import 'bootstrap/dist/css/bootstrap.min.css'
import './App.css'
import registerServiceWorker from './registerServiceWorker';

ReactDOM.render(<App />, document.getElementById('root'));
registerServiceWorker();

Am I missing something?

To make dropdown menu and other js stuff work in 4th Bootstrap you need just follow next steps: install with npm to dependencies:

npm i --save bootstrap jquery popper.js

add it to index.js

import 'bootstrap';
import 'bootstrap/dist/css/bootstrap.css';
import 'bootstrap/dist/js/bootstrap.js';
import $ from 'jquery';
import Popper from 'popper.js';

all steps are taken from here
