use id selector instead class selector. for example call dropdown like this : html:

<a class='dropdown-trigger' id="dropdowner" href='#' data-target='dropdown1'>Drop Me!</a> <ul id='dropdown1' class='dropdown-content'> <li><a href="#!">one</a></li> <li><a href="#!">two</a></li> <li class="divider" tabindex="-1"></li> <li><a href="#!">three</a></li> <li><a href="#!"><i class="material-icons">view_module</i>four</a></li> <li><a href="#!"><i class="material-icons">cloud</i>five</a></li> </ul>

js : $('#dropdowner').dropdown();
