jquery siblings removeclass
<p>Toggleclass works perfectly but siblings dont. 
<br/>I miss something and the class "corrente" dont remove if i click in another button h1.</p>

<p>Structure code:</p>

<pre><code>$(document).ready(function(){

     $("ul.box").addClass(" invisivel");
$("#menu a").click(function(){
    $(this).next("ul.box").slideToggle("slow")
    .siblings("ul.box:visible").slideUp("slow");
    $(this).children("h1").toggleClass("corrente")
    .siblings("h1").removeClass("corrente");
    return false;
});


});  
</code></pre>

<p>Html code:</p>

<pre><code>&lt;div id="menu"&gt;
&lt;a href=""&gt;&lt;h1 class="link-titulo"&gt;Oficina da África&lt;/h1&gt;&lt;/a&gt;           

&lt;ul class="box"&gt;                    
                    &lt;li&gt;xxx&lt;/li&gt;

&lt;/ul&gt;

&lt;a href=""&gt;&lt;h1 class="link-titulo"&gt;Calendário/Currículo&lt;/h1&gt; &lt;/a&gt;

&lt;ul class="box"&gt;
                    &lt;li&gt;xxx&lt;/li&gt;

&lt;/ul&gt;&lt;/div&gt;
</code></pre>
