Visual Studio Code – Bootstrap not loading properly

I download bootstrap and linked the css and js bundle files yet bootstrap components are not loading properly.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
    <link rel="stylesheet" href="css/bootstrap.css">
</head>
<body>
    <div class="dropdown">
        <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
          Dropdown button
        </button>
        <div class="dropdown-menu" aria-labelledby="dropdownMenuButton">
          <a class="dropdown-item" href="#">Action</a>
          <a class="dropdown-item" href="#">Another action</a>
          <a class="dropdown-item" href="#">Something else here</a>
        </div>
      </div>

    You have not included your bootstap version. If you are using Bootstrap 5, add data-bs-toggle="dropdown" to you button element – that might be a reason why it does not work –> see here: https://getbootstrap.com/docs/5.0/components/dropdowns/

    In Bootstrap 5 components like dropdowns rely on data attributes or JavaScript for initialization. For dropdowns the proper data attribute is data-bs-toggle="dropdown".
