Side-nav doesn't work in material design based mobile app

Question

I wrote a simple page with side-nav functionality. However side-nav fails to open up when clicked on top left corner. My code:
Html:

<nav>
            <ul class="right hide-on-med-and-down">
                <li><a href="#!">First Sidebar Link</a></li>
                <li><a href="#!">Second Sidebar Link</a></li>
            </ul>
            <ul id="slide-out" class="side-nav">
                <li><a href="#!">First Sidebar Link</a></li>
                <li><a href="#!">Second Sidebar Link</a></li>
            </ul>
            <a href="#" data-activates="slide-out" class="button-collapse"><i class="mdi-navigation-menu"></i></a>
        </nav>


        <div class="row">
            <div class="card logincard">
                <form class="col s12">
                    <h5>Enter your mail id to reset your password: </h5>
                  <div class="row">
                    <div class="input-field col s12">
                      <input id="mail" type="email" class="validate">
                      <label for="mail">Mail</label>
                    </div>
                  </div>
                  <div class="row">
                    <a class="waves-effect waves-light btn" style="background: #4099FF;">Submit</a>
                  </div>
                </form>
            </div>
        </div>  

JS:

(function($){
          $(function(){

            $('.button-collapse').sideNav();

          }); // end of document ready
        })(jQuery); // end of jQuery name space

How can I fix it?

Answer 1

You need to place your icon (or something) inside a class left UL

<nav>
  <ul class="left show-on-med-and-down">
    <li><a href="#" data-activates="slide-out" class="button-collapse"><i class="mdi-navigation-menu"></i></a></li>
  </ul>
  <!-- etc -->
