Bootstrap Dropdown is not working in React

问题

I include a dropdown button to React from bootstrap Dropdowns, But it is not working and shows as a normal button. Can you give me a solution for this?

<div className="dropdown">
    <button className="btn btn-secondary 
                 dropdown-toggle" 
                 type="button" 
                 id="dropdownMenuButton"
                 data-toggle="dropdown"
                 aria-haspopup="true" 
                 aria-expanded="false">
                 Dropdown button
    </button>
            <div className="dropdown-menu" aria-labelledby="dropdownMenuButton">
                <a className="dropdown-item" href="#">Action</a>
                <a className="dropdown-item" href="#">Another action</a>
                <a className="dropdown-item" href="#">Something else here</a>
            </div>
</div>

The output is a normal button like this.

Dropdowns are not working without popper.js and jquery.js.

So please install popper.js and jquery.js in your system using npm install popper.js jquery --save and don't forget to include it.
