How to use .next() over several elements
<p>This is the current code:</p>

<pre><code>$("input[name='content_use']").click(function() {
    if ($(this).is(":checked")){
        $(this).closest('tr').next().show();
        $(this).closest('tr').next().next().show();
        $(this).closest('tr').next().next().next().show();
    } else{
        $(this).closest('tr').next().hide();
        $(this).closest('tr').next().next().hide();
        $(this).closest('tr').next().next().next().hide();
    }
}); 
</code></pre>

<p><strong>EDIT:</strong> </p>

<p>As you can see I must to use <code>next()</code> repeatedly to reach successive rows. How can I code this shorter? </p>
