WordPress / CSS-子菜單懸停下拉樣式添加到導航欄

Question

我有一個響應式導航欄，已將其添加到WordPress主題中。 但我希望將子菜單下拉菜單添加到響應式導航欄中，但不確定如何執行此操作。 我是PHP和WordPress的新手。

的HTML

                <?php

                $args = array(
                    'theme_location' => 'primary'
                );

                ?>

                <?php wp_nav_menu(  $args ); ?>
        </ul>
            <a href="#" id="pull">Menu</a>

            $(pull).on('click', function(e) {
                e.preventDefault();
                menu.slideToggle();
            });

            $(window).resize(function(){
                var w = $(window).width();
                if(w > 320 && menu.is(':hidden')) {
                    menu.removeAttr('style');
                }
            });
        });
    </script>

額外的CSS嘗試

ul.sub-menu { /* this targets all sub menus */
    display: none; /* hide all sub menus from view */
    position: absolute;
    z-index: 10;
    top: 40px; /* this should be the same height as the top level menu -- height + padding + borders */
}

ul.sub-menu li { /* this targets all submenu items */

    width: 100px; /* set to the width you want your sub menus to be. This needs to match the value we set below */
}
ul.sub-menu li a { /* target all sub menu item links */
    padding: 5px 10px; /* give our sub menu links a nice button feel */
}
ul.sub-menu li:hover {
    display: block; /* show sub menus when hovering over a parent */
}

我已經調整了您的某些CSS和HTML，請立即檢查其工作情況。

主要問題是在nav的高度中，我也將a#pull的位置更改為ul的頂部。

  $(function() { var pull = $('#pull'); menu = $('nav ul'); menuHeight = menu.height(); $(pull).on('click', function(e) { e.preventDefault(); menu.slideToggle(); }); $(window).resize(function() { var w = $(window).width(); if (w > 320 && menu.is(':hidden')) { menu.removeAttr('style'); } }); }); 

 nav { width: 100%; color: #fff; background: #86c024; font-size: 11pt; position: relative; height: 100%; overflow: hidden; } nav ul { padding: 0; margin: 0 auto; max-width: 1000px; width: 100%; } nav li { display: inline; float: left; height: 40px; } .clearfix:before, .clearfix:after { content: " "; display: table; } .clearfix:after { clear: both; } .clearfix { *zoom: 1; } nav a { color: #fff; display: inline-block; width: auto; text-align: center; text-decoration: none; line-height: 40px; } nav li a { padding: 0 10px; border-right: 1px solid #fff; box-sizing: border-box; -moz-box-sizing: border-box; -webkit-box-sizing: border-box; } nav li a:link, a:visited { color: white } nav li:last-child a { border-right: 0; } nav a:hover { background: #2098d1; } nav ul li.current-menu-item a:link, .site-header nav ul li.current-menu-item a:visited, .site-header nav ul li.current-page-ancestor a:link, .site-header nav ul li.current-page-ancestor a:visited { font-weight: bold; background: #2098d1; } nav a#pull { display: none; } @media screen and (max-width: 600px) { nav { height: auto; } nav ul { width: 100%; display: block; height: auto; } nav li { width: 100%; float: left; position: relative; } nav li a { border-bottom: 1px solid #fff; border-right: 1px solid #fff; } nav a { text-align: left; width: 100%; text-indent: 25px; } } @media only screen and (max-width: 600px) { nav { border-bottom: 0; } nav ul { display: none; height: auto; } nav a#pull { display: block; background: #86c024; width: 100%; position: relative; } nav a#pull:after { content: ""; background: url('img/nav-icon.png') no-repeat; width: 30px; height: 30px; display: inline-block; position: absolute; right: 15px; top: 10px; } } @media only screen and (max-width: 320px) { nav li { display: block; float: none; width: 100%; } nav li a { border-bottom: 1px solid #576979; } } } 

 <nav> <a href="#" id="pull">Menu</a> <ul> <li><a href="#">Home</a> </li> <li><a href="#">Home</a> </li> <li><a href="#">Home</a> </li> <li><a href="#">Home</a> </li> <li><a href="#">Home</a> </li> </ul> </nav>
