I used one of the CSS templates and the menu in it has no dropdown menu so I added the dropdown mene to it. The problem now is sometimes when I put the mouse over one of the tabs/options that has a dropdown menu (sub-menu), I cannot select anything from this dropdown menu because it is quickly disappeared and I don't know why this happened.
The HTML code for this menu:
<div class="topnav">
<ul class="menu" runat="server" >
<li><a href="Default.aspx">Home</a></li>
<li><a href="Services.aspx">Services</a>
<ul>
<li><a href="#">Service #1</a></li>
<li><a href="#">Service #2</a></li>
<li><a href="#">Service #3</a></li>
</ul>
</li>
<li><a href="#">Items</a>
<ul>
<li><a href="#">Item #1</a></li>
<li><a href="#">Item #2</a></li>
<li><a href="#">Item #3</a></li>
<li><a href="#" target="_blank">Item #4</a></li>
<li><a href="#" target="_blank"">Item #5</a></li>
<li><a href="#" target="_blank">Item #6</a></li>
<li><a href="#">Item #1</a></li>
</ul>
</li>
<li><a href="#">About</a></li>
<li><a href="#">Contact Us</a></li>
<li><a href="#">Help</a></li>
</ul>
<div class="clr"></div>
</div>
The css code for this menu is:
@charset "utf-8";

ul.menu li ul { font-family:"Liberation sans", Arial, Helvetica, sans-serif;}

.topnav { padding:0; margin:0; width:966px; height:53px; background: url(images/bg_menu.gif) top repeat-x; }

JQuery code:
jQuery(document).ready(function($){
// menu smothness
$('.menu li').click(function() {
window.location = $(this).find('a:first').attr('href');
});
var dropdown_level = 0;
$('.menu li ul').parent().find('a:first').addClass('have_submenu');
$('.menu').children('li').children('a').addClass('top_level');
$('.menu').children('li').children('a').removeClass('have_submenu');
$('.menu li').hover(function(){
if(dropdown_level == 0){
$('.menu').find('a').removeClass('have_submenu_hover');
$(this).addClass('li_hover_main');
$(this).children('a').addClass('a_hover_main');
$('.menu ul').parent().find('a:first').addClass('have_submenu');
$('.menu').children('li').children('a').addClass('top_level');
$('.menu').children('li').children('a').removeClass('have_submenu');
}
$(this).find('ul:first').stop(true,true).slideDown(200).show();
$(this).find('a:first').addClass('have_submenu_hover');
$('.menu').children('li').children('a').removeClass('have_submenu_hover');
dropdown_level++;
},function(){
$(this).find('ul:first').stop(true,true).slideUp(0);
$(this).find('a:first').removeClass('have_submenu_hover');
dropdown_level--;
if(dropdown_level == 0){
$(this).removeClass('li_hover_main');
$(this).children('a').removeClass('a_hover_main');
}
});
// END of menu smothness
});
Here is a snapshot for the menubar that I have:
I used a hoverIntent script to fix this effect. You are literally leaving one anchor so the hover is gone when you mouse out. A way to fix this is to delay the hover effect so it stays long enough for users to mouse over.

Then something like
$('.main-nav > ul > li').hoverIntent({
timeout: 300,
over: function () {
$(this).addClass('hover')
},
timeout: 300,
out: function () {
$(this).removeClass('hover')
}
});
