最初使用 CSS 将其隐藏：

.main-menu + ul { display:none; }

我看到了你最后的作品。做得好。有点晚了，我知道你不需要它，但正如我在评论中所承诺的那样。这是小提琴。

HTML

<ul class="menu">
    <li>Home</li>
    <ul>
        <li>Element 1</li>
        <li>Element 2</li>
        <li>Element 3</li>
    </ul>
    <li>Services</li>
    <ul>
        <li>Element 4</li>
        <li>Element 5</li>
        <li>Element 6</li>
    </ul>
</ul>

Javascript

$(document).ready( function() {
    $('li').click(function(){
        $('ul.menu ul').slideUp('fast'); // hides all the submenu that are open
            var submenu = $(this).next('ul');
        if ( $(this).next('ul').is(':visible') ) {
            submenu.slideUp('fast'); // if is already open, it will hide it. if you don't care about one being always open, delete this if statement and keep the last line slideToggle.
        } else {
            submenu.slideToggle('fast'); // toggles within open and close.
        }
    });
});

CSS

ul.menu { margin: 0; padding: 0; width: 200px; font-family: arial;}
ul.menu ul { display: none; }
ul.menu li { list-style: none; border: 1px solid #CCCCCC; padding: 10px; }
ul.menu ul { padding: 0; background: #EEEEEE  }
