<p>Attach the click handler to anchor tag instead of just accordion. Something like this </p>

<pre><code>$(".accordion a").click(function (e) {
    var closestLi = $(this).closest('li');
    if (closestLi.hasClass('active')) {
        closestLi.children('ul').slideUp();
        closestLi.removeClass('active');
    } else {
        closestLi.children('ul').slideDown();
        closestLi.addClass('active');
    }

<p>You could make your code check if you're actually clicking the li element. If not we do nothing in the click handler.</p>

<p>I think this is the cleanest solution:</p>

<p><div class="snippet" data-lang="js" data-hide="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>        $( ".accordion").click(function(e) {
            // Check if the parent of the target is the same as the .accordion we bound the event to
            if (e.target.parentElement !== this) return;
            
            if ($(this).hasClass('active')){
                $(this).children('ul').slideUp();
                $(this).removeClass('active');
            }else{
                $(this).children('ul').slideDown();
                $(this).addClass('active');
            }
        });</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"&gt;&lt;/script&gt;
&lt;ul&gt;
                       &lt;li&gt;&lt;a href="#"&gt;Link example 1&lt;/a&gt; &lt;/li&gt;
                       &lt;li class="accordion"&gt;
                           &lt;a href="#"&gt;Link example 2 with accordion&lt;/a&gt;
                           &lt;ul style="display: none;"&gt;
                               &lt;li&gt;&lt;a href="#"&gt;Link inside accordion 2&lt;/a&gt;&lt;/li&gt;
                               &lt;li&gt;&lt;a href="#"&gt;Link inside accordion 3&lt;/a&gt;&lt;/li&gt;
                           &lt;/ul&gt;
                       &lt;/li&gt;
                       &lt;li&gt;&lt;a href="#"&gt;Smth&lt;/a&gt; &lt;/li&gt;
                   &lt;/ul&gt;</code></pre>
</div>
</div>
</p>


blocks|key|3822996|text|只需对子元素使用event.stopPropagation()即可。你甚至不需要一个类|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3822997|$("li+>+ul").click(function(event){

<p>Just use event.stopPropagation() on the child elements. You don't even need a class</p>

<pre><code>$("li &gt; ul").click(function(event){
    event.stopPropagation();
});
</code></pre>

<p>fiddle: <a href="https://jsfiddle.net/Nillervision/0gzx9Lv8/#base" rel="nofollow">https://jsfiddle.net/Nillervision/0gzx9Lv8/#base</a></p>


<p>I have one problem. Actually I have this structure: <a href="https://jsfiddle.net/e7bm4mcf/" rel="nofollow"><code>jsfiddle link</code></a></p>

<p>When I click on <code>"Link example 2 with accordion"</code> it does expand the ul.<br> But when I click on any link inside this, it becomes hidden because links under 
<code>"Link example 2 with accordion"</code> are inside <code>&lt;li class="accordion"&gt;</code>. </p>

<p>My question is: How can I stop this behaviour?</p>
