Bootstrap 4 navwalker -多级菜单
Bootstrap 4 navwalker -多级菜单
提问于 2018-07-18 17:40:46
我在我的Wordpress项目中使用了this nav walker。例如，我想创建多级菜单。我需要做些什么才能让它正常工作？或者它可能是另一个支持多级菜单的BS4 walker？

- 添加此css
ul.dropdown-menu li > ul.dropdown-menu{ left: 100%；top: 0；} ul.dropdown-menu li:hover > ul.dropdown-menu，ul.dropdown-menu li:focus > ul.dropdown-menu{ display: block }
- 从
&& 0 === $depth-wp-bootstrap-navwalker.php中删除以下代码引导
原始代码：
如果( isset( $args->has_children ) && $args->has_children && 0 === $depth && $args->depth >1){
编辑完成后：
如果( isset( $args->has_children ) && $args->has_children && $args->depth >1) {

Bulding simple menu list -在这里的用户贡献笔记(第一个)中，你可以找到使用菜单数组数据构建菜单的代码，它很简单，可以根据需要进行修改。
代码如下：
<?php
// Intented to use bootstrap 3.
// Location is like a 'primary'
// After, you print menu just add create_bootstrap_menu("primary") in your
preferred position;
#add this function in your theme functions.php
function create_bootstrap_menu( $theme_location ) {
if ( ($theme_location) && ($locations = get_nav_menu_locations()) && isset($locations[$theme_location]) ) {
$menu_list = '<nav class="navbar navbar-default">' ."\n";
$menu_list .= '<div class="container-fluid">' ."\n";
$menu_list .= '<!-- Brand and toggle get grouped for better mobile display -->' ."\n";
$menu_list .= '<div class="navbar-header">' ."\n";
$menu_list .= '<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">' ."\n";
$menu_list .= '<span class="sr-only">Toggle navigation</span>' ."\n";
$menu_list .= '<span class="icon-bar"></span>' ."\n";
$menu_list .= '<span class="icon-bar"></span>' ."\n";
$menu_list .= '<span class="icon-bar"></span>' ."\n";
$menu_list .= '</button>' ."\n";
$menu_list .= '<a class="navbar-brand" href="' . home_url() . '">' . get_bloginfo( 'name' ) . '</a>';
$menu_list .= '</div>' ."\n";
$menu_list .= '<!-- Collect the nav links, forms, and other content for toggling -->';
$menu = get_term( $locations[$theme_location], 'nav_menu' );
$menu_items = wp_get_nav_menu_items($menu->term_id);
$menu_list .= '<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">' ."\n";
$menu_list .= '<ul class="nav navbar-nav">' ."\n";
foreach( $menu_items as $menu_item ) {
if( $menu_item->menu_item_parent == 0 ) {
$parent = $menu_item->ID;
$menu_array = array();
foreach( $menu_items as $submenu ) {
if( $submenu->menu_item_parent == $parent ) {
$bool = true;
$menu_array[] = '<li><a href="' . $submenu->url . '">' . $submenu->title . '</a></li>' ."\n";
}
}
if( $bool == true && count( $menu_array ) > 0 ) {
$menu_list .= '<li class="dropdown">' ."\n";
$menu_list .= '<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">' . $menu_item->title . ' <span class="caret"></span></a>' ."\n";
$menu_list .= '<ul class="dropdown-menu">' ."\n";
$menu_list .= implode( "\n", $menu_array );
$menu_list .= '</ul>' ."\n";
} else {
$menu_list .= '<li>' ."\n";
$menu_list .= '<a href="' . $menu_item->url . '">' . $menu_item->title . '</a>' ."\n";
}
}
// end <li>
$menu_list .= '</li>' ."\n";
}
$menu_list .= '</ul>' ."\n";
$menu_list .= '</div>' ."\n";
$menu_list .= '</div><!-- /.container-fluid -->' ."\n";
$menu_list .= '</nav>' ."\n";
} else {
$menu_list = '<!-- no menu defined in location "'.$theme_location.'" -->';
}
echo $menu_list;
}
