What is the best way to activate materialise pop-up menus in a React application?

Looking to enhance my React app by adding a NavBar with dropdown functionality. Here's the code snippet:

<ul id="dropdown1" className="dropdown-content">
          <li><NavLink to="/create">Create lessons</NavLink></li>*/}
                <li><NavLink to="/lessons">Lessons</NavLink></li>
                <li><NavLink to="/quizes">Quizes</NavLink></li>
                <li><NavLink to="/quizcreator">Create QuizGame</NavLink></li>
                <li></li>
                <li></li>
        </ul>

  <nav>
    <div className="nav-wrapper">
      <a href="#!" className="brand-logo">Logo</a>
      <ul className="right hide-on-med-and-down">
        <li><NavLink to="/home">Home</NavLink></li>
        <li><a className="dropdown-trigger" href="#!" data-target="dropdown1">Dropdown<i
            className="material-icons right">arrow_drop_down</i></a></li>
        <li><a href="/" onClick={logoutHandler}>Logout</a></li>
      </ul>
    </div>
  </nav>

Based on the information provided in the official documentation, you can activate all your dropdowns by using the following code snippet:

document.addEventListener('DOMContentLoaded', function() {
  var elems = document.querySelectorAll('.dropdown-trigger');
  var instances = M.Dropdown.init(elems);
});

For a practical demonstration, refer to this example (preferably open it in full-page mode):

document.addEventListener('DOMContentLoaded', function() {
  var elems = document.querySelectorAll('.dropdown-trigger');
  var instances = M.Dropdown.init(elems);
});

Answer №3

Make sure to include an onclick event in your second list item ("li"). Pass the event object as a parameter, and then call the dropdown() function by retrieving the classname from the event object.

<li>
    <a className="dropdown-trigger" href="#!" onclick{(e) => e.target.className.dropdown();} data-target="dropdown1">
       Dropdown<i className="material-icons right">arrow_drop_down</i>
    </a>
</li>

Just follow these simple steps to make it work effortlessly!

Simply insert the following code snippet into your JavaScript file:

document.addEventListener('DOMContentLoaded', function() {
  var elems = document.querySelectorAll('.dropdown-trigger');
  var instances = M.Dropdown.init(elems);
});

If you're facing issues with the dropdown functionality, it's probably because you haven't initialized it properly! Consider using a different framework like MDbootstrap, which offers a React version and comprehensive documentation without any intrusive ads.
