我有一个有趣的问题，过去几天我一直在尝试解决。我创建了第二个导航菜单，并通过将此代码添加到我的 custom_functions.php 将其添加到论文 1.8.5 的侧边栏：
/* Add second menu to sidebar 1*/
register_nav_menu('secondary', 'Secondary Menu');
function secondary_menu() {
wp_nav_menu( array( 'container_class' => 'secondary_menu', 'theme_location' => 'secondary' ) );
}
add_action('thesis_hook_before_sidebar_1','secondary_menu');
然后，我通过将此 css 添加到 custom.css 来为菜单项创建图标：
/* Menu Container */
.custom .sidebar .menu {
list-style: none;
padding: 0;
margin: 0 0 0 10px;
width: 190px;
height: 190px;
position: relative;
}
/* Submenu Container */
.custom .sidebar .sub-menu {
list-style: none;
padding: 0;
margin: 0;
width: 190px;
height: 45px;
position: relative;
}
/* Facebook */
.custom #menu-item-15470 a {
display:block;

菜单图标在所有浏览器（包括移动 chrome）上正确显示，但在移动 safari（仅显示链接）上不正确。
它应该看起来如何：
