引导下拉菜单

我想在Wordpress中创建一个像这样的下拉菜单

<div class="dropdown">
                    <li class="dropdown-style" type="button" id="dropdownMenu1" data-hover="dropdown" aria-haspopup="true" aria-expanded="true">
                        Golfbestemmingen <span class="caret"></span>
                    </li>
                    <ul class="dropdown-menu" aria-labelledby="dropdownMenu1">
                        <li><a href="#">Action</a></li>
                        <li><a href="#">Another action</a></li>
                        <li><a href="#">Something else here</a></li>
                        <li><a href="#">Separated link</a></li>
                    </ul>
                </div>

我现在的代码

<?php wp_nav_menu( array('menu' => 'Hoofd Menu','container_class' => 'dropdown','items_wrap' => '%3$s')); ?>
