jQuery drop down menu does not appear - php

Question

I am trying to make a drop-down menu using jQuery/JavaScript, but my menu won't show anything.
Here is my code:
JavaScript:
function toggleMenu(target){
if($(target).css("display")=='none'){
$("#drop_down, drop_menu").hide(500);
$(target).toggle(500);
}
header.php
<?php
?>
<div id="header" class="absolute" >
<ul>
<li class="float_left"><p class="pointer" onclick="toggleMenu('#drop_search')">Search</p></li>
<li class="float_left"><p class="pointer" onclick="toggleMenu('#drop_login')">Log in</p></li>
<li class="float_left"><p class="pointer" onclick="toggleMenu('#drop_chart')">My Cart</p></li>
<li class="float_left"><p class="pointer" onclick="toggleMenu('#drop_menu')">Menu</p></li>
</ul>
<div class="clear_both"></div>
<br/>
<div id="drop_down"class="right">
<div id="drop_search" class="hidden">
<p>Search</p>
</div>
<div id="drop_login" class="hidden">
<p>login</p>
</div>
<div id="drop_chart" class="hidden">
<p>cart</p>
</div>
<div id="drop_menu" class="hidden">
<p>menu</p>
</div>
</div>
</div>

Can anyone can help ?

Answer 1

Remove your class="hidden" and set default to style="display: none" (or hide on page load).

Answer 2

You have a sintaxe error in your function
Try with this function
function toggleMenu(target){
if($(target).is(":hidden")){
$("#drop_down div").hide(500);
}
$(target).toggle(500);
}
And give me some feedback...

Answer 3

This code might work as per your requirement. I have not changed your code just remove class="hidden" entirely.
Note: You have not mention your css so i assume as per class names defined by you.
Please let me know if i am lagging some where....
