css - 如何让下拉菜单固定在同一位置

标签 css drop-down-menu menu nav submenu

我的导航中有一个下拉菜单。现在每个下拉菜单都在父元素下下拉。但是，我希望每个下拉菜单都在同一位置下拉。 (就像这个菜单 - https://themify.me/demo/#theme=peak )。任何人都可以提供任何解决方案吗？提前致谢。

这是一个示例 jsfiddle - https://jsfiddle.net/5vedgn95/

我的 header.php

<?php
?>
<!DOCTYPE html>
<html <?php language_attributes(); ?>>
<head>
<meta charset="<?php bloginfo( 'charset' ); ?>">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="profile" href="http://gmpg.org/xfn/11">
<link rel="pingback" href="<?php bloginfo( 'pingback_url' ); ?>">

<?php wp_head(); ?>
</head>

<body <?php body_class(); ?>>
<div id="ht-page">
	<header id="ht-masthead" class="ht-site-header">
		<div class="ht-container ht-clearfix">
			<div id="ht-site-branding">
				<?php 
				if ( function_exists( 'has_custom_logo' ) && has_custom_logo() ) :
					the_custom_logo();
				else : 
					if ( is_front_page() ) : ?>
						<h1 class="ht-site-title"><a href="<?php echo esc_url( home_url( '/' ) ); ?>" rel="home"><?php bloginfo( 'name' ); ?></a></h1>
					<?php else : ?>
						<p class="ht-site-title"><a href="<?php echo esc_url( home_url( '/' ) ); ?>" rel="home"><?php bloginfo( 'name' ); ?></a></p>
					<?php endif; ?>
					<p class="ht-site-description"><a href="<?php echo esc_url( home_url( '/' ) ); ?>" rel="home"><?php bloginfo( 'description' ); ?></a></p>
				<?php endif; ?>
			</div><!-- .site-branding -->

			<nav id="ht-site-navigation" class="ht-main-navigation">
				<div class="toggle-bar"><span></span></div>
				<?php 
				wp_nav_menu( array( 
					'theme_location' => 'primary', 
					'container_class' => 'ht-menu ht-clearfix' ,
					'menu_class' => 'ht-clearfix',
					'items_wrap' => '<ul id="%1$s" class="%2$s">%3$s</ul>',
				) ); 
				?>
			</nav><!-- #ht-site-navigation -->
		</div>
	</header><!-- #ht-masthead -->

	<div id="ht-content" class="ht-site-content ht-clearfix">

最佳答案

从 li 中删除 position: relative，并将其添加到 ul 中，这样子菜单就是 absolutely 位于 ul 顶部的 100%。

如果您希望子菜单跨越父级的整个宽度，请从 .ht-main-navigation ul ul 中删除 width: 900px; 并添加 right: 0(我没有这样做，因为你没有要求它)
