Answer 1

hey, you can use pure CSS e.g. position:fixed;top:30px;left:30px;z-index:100;

second jQuery solution:

CSS:

<style type="text/css">
#mainmenu{position:absolute;left:30px;top:30px;z-index:100;}
#content{height:2000px;}
</style>

jQuery

<script type="text/javascript">
$(function(){
    $(window).scroll(function(){
        $('#mainmenu').animate({top:$(window).scrollTop()+30},500);
    });
});
</script>

HTML:

<div id="mainmenu">
<ul>
<li><a href="">link 1</a></li>
<li><a href="">link 2</a></li>
<li><a href="">link 3</a></li>
<li><a href="">link 4</a></li>
</ul>
</div>
<div id="content">
</div>
