Answer №1

Ensure your button is properly linked to your div

<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>

Make sure the "aria-labelledby" attribute matches the button's ID value of "dropdownMenuButton"

This information can also be found in the Bootstrap documentation

Check out this example code snippet for creating a Bootstrap 4 dropdown navbar:

<nav class="navbar navbar-expand-lg navbar-light" style="background-color: #fdfeff;">
  <a class="navbar-brand" href="#">
    <img src="images\logo1.png" width="200" height="80" class="d-inline-block align-top" alt="">
  </a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navCollapse"
    aria-controls="navCollapse" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>
  <div class="collapse navbar-collapse justify-content-center" id="navCollapse">
    <ul class="navbar-nav">
      <li class="nav-item active">
        <a class="nav-link" href="index.html">Home <span class="sr-only">(current)</span></a>
      </li>
      <li class="navbar-nav dropdown">
        <a class="nav-link dropdown-toggle" type="button" id="dropdown01"
          data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
          Behandelingen
        </a>
        <div class="dropdown-menu" aria-labelledby="dropdown01">
          <a class="dropdown-item" href="sportmassage.html">Sportmassage</a>
          <a class="dropdown-item" href="#">Massagetherapie</a>
          <a class="dropdown-item" href="#">Ontspanningsmassage</a>
        </div>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Afspraak maken</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Tarieven</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Contact</a>
      </li>
    </ul>
  </div>
</nav>
