After click, reverse animation on jQuery (Show/Hide)

Question

I'm trying to use the:

$(document).ready(function() {
    $('#showmenu1').click(function() {
            $('.menu1').slideDown("slow");
    });
});

Effect in jQuery to make a div appear when a trigger is clicked, which it does very successfully. However I want the animation to reverse to make the div disappear, when that same trigger is clicked again. The effect I want to make is:

$(document).ready(function() {
    $('#showmenu1').click(function() {
            $('.menu1').slideUp("slow");
    });
});

Any help would be greatly appreciated.

HTML Example:

<section id="showmenu1" style="background-color:#09F; color:#fff">
    <h1>Show Div</h1>
</section>
<div class="menu1" style="display: none; background-color:#09F; color:#fff; padding:0; margin:0">
    <ul style="padding:0px; margin:0px; position: relative; text-align: center;">
        <li>
            <h1 style="margin-top:0">Hello Div</h1>
            <p style="margin-top:0">Div is shown</p>
        </li>
    </ul>
</div>

Cheers

ToggleSimply use slideToggle instead:

$(document).ready(function() {
    $('#showmenu1').click(function() {
            $('.menu1').slideToggle("slow");
    });
});

Try this:

$("div").click(function() {
  $(this).hide("slide", {
    direction: "down"
  }, 1000);
});
