slidedown function is weird. - need help

ok . so I made a dropdown menu using slidedown fungtion in jquery and I made it work. my problems comes when I load the page it stays open and when I browse the site same thing happen they stay open till the page is loaded.


<script type="text/javascript">
$(document).ready(function(){
// box 1 close
$(".pos-2 .btn").click(function(event){
   $(".pos-2 ul:hidden").slideDown("slow");
});

$(".pos-2 .close").click(function(event){
   $(".pos-2 ul:visible").slideUp("fast");
});


$(".pos-1 .btn").click(function(event){
   $(".pos-1 ul:hidden").slideDown("slow");
});

$(".pos-1 .close").click(function(event){
   $(".pos-1 ul:visible").slideUp("fast");
});

$(".drop ul:visible").slideUp("fast");

});
</script>


ok I`m not an expert, I only know a few about javascript and jquery.
I would really appreciate some help with this,. I don`t know if I`m going to the right direction with this slidedown function or should I try something else. you can see the working example here http://www.wickedticketsny.net
