This is my first time using JQuery in any of my projects.
I have implemented the superfish menu.
On some of my pages I have a horizontal scroll. I would like to make the menu float on the center of the page as the page is scrolled.
Also I need to make sure that the submenu on the far right hand side of the menu does not open up off the page. When I hover on the right most element it opens up half off the page.
Any ideas on how to fix these two things?
I'm perfectly willing to use a different Jquery menu if there is a better one that has these features built in...
Thanks!
javascrupt call in my page:
$(document).ready(function () {
$("ul.sf-menu").supersubs({
minWidth: 12, // minimum width of sub-menus in em units
maxWidth: 27, // maximum width of sub-menus in em units
extraWidth: 1 // extra width can ensure lines don't sometimes turn over
// due to slight rounding differences and font-family
}).superfish({ animation: { opacity: 'show', height: 'show' }, autoArrows: false }); // call supersubs first, then superfish, so that subs are
// not display:none when measuring. Call before initialising
// containing tabs for same reason.
I can post any more code that is needed, but there is quite a lot of code in the superfish files so i'm not sure what I should post.
I found this script and it works well, however when I scroll right the horizonal menu starts to stack so the menu items are side by side rather then vertical. I want to modify this to keep the menu horizonal...
