Jquery slideUp menu disappears after slideDown
<p>I'm working on a menu that should slide down when I click on an anchor <code>&lt;a&gt;</code>, and it should slide up when I click on the <code>&lt;body&gt;</code> of the page (the <code>&lt;a&gt;</code> tag is included in the body).
I'm currently using jQuery.</p>

<p>The problem is that after the first 2 click's (first on the  tag result: the menu appears; second click on the <code>&lt;body&gt;</code>), the menu disappears, but when I click again on the <code>&lt;a&gt;</code> tag the menu slides both down an up at the same time?</p>

<p>Here is the code:</p>

<pre><code>$(function() {
    $('.sch_option a').click(function() {           
        $('.sch_option .sch_more_option_extend').slideDown(150, function(){             
            $('body').click(function() {
                $('.sch_option .sch_more_option_extend').slideUp(100);          
            }); 
        });
    });
});
</code></pre>
