SuckerTree Horizontal Menu

Author: Dynamic Drive

SuckerTree Horizontal Menu is a CSS and DOM hybrid menu that's list based and supports multiple levels of sub menus. The trick to SuckerTree is a small adoptable piece of JavaScript that crawls the inner levels of a list menu and assigns the appropriate show/hide and positioning behavior to them. You can even have multiple SuckerTree menus on the same page.

The CSS:

<style type="text/css">

.suckertreemenu ul{

Great script!! THanks to the creators.

Here is the fix I came up with for IE7 submenu disappearence. A little change to the javascript:

Change the .offsetWidth by -20. You may need to play with the offset if necessary, but this will fix all the submenus.

}
else{ //else if this is a sub level menu (ul)
ultags[t].style.left=ultags[t-1].getElementsByTagName("a")[0].offsetWidth-20+"px" //position menu to the right of menu item that activated it
ultags[t].parentNode.getElementsByTagName("a")[0].className="subfoldericon"
}

HOPE THIS HELPS!!!

I am having problems with this on Firefox 2.0.0.11. It doesn't behave well when there are multiple ul li ul li. I installed/de-installed the Holly Hack with no luck. Any ideas?

When I try to go down the menu in IE sometimes, the drop down menu disappears.

This fixed my IE7 submenu disappearence:

Just give set a background to the link items in the submenu's:

/* Sub level menu links style */
.suckertreemenu ul li ul li a{
background-color: #FFFFFF;
}

For screenreaders, to be able to read menu that 'hidden' hides of:

/*1st sub level menu*/
.suckertreemenu ul li ul
{
position: absolute;
top: 1em; /* no need to change, as true value set by script */
display: block;
left: -999em; /* using left instead of display to hide menus because display: none isn't read by screen readers */
width: 145px;
padding: 2em 0 0 0;
margin:0;
white-space:normal;
}

And then in script:

function buildsubmenus_horizontal(){
for (var i=0; i<menuids.length; i++){
var ultags=document.getElementById(menuids[i]).getElementsByTagName("ul")
for (var t=0; t<ultags.length; t++){
if (ultags[t].parentNode.parentNode.id==menuids[i]){ //if this is a first level submenu
ultags[t].style.top=ultags[t].parentNode.offsetHeight+"px" //dynamically position first level submenus to be height of main menu item
ultags[t].parentNode.getElementsByTagName("a")[0].className="mainfoldericon"
}
else{ //else if this is a sub level menu (ul)
ultags[t].style.left=ultags[t-1].getElementsByTagName("a")[0].offsetWidth+"px" //position menu to the right of menu item that activated it
ultags[t].parentNode.getElementsByTagName("a")[0].className="subfoldericon"
}
ultags[t].parentNode.onmouseover=function()
{
//this.getElementsByTagName("ul")[0].style.visibility="visible"
this.getElementsByTagName("ul")[0].style.left="0em"
}
ultags[t].parentNode.onmouseout=function()
{
//this.getElementsByTagName("ul")[0].style.visibility="hidden"
this.getElementsByTagName("ul")[0].style.left="-999em"
}
}
}
}

The above code is great! But I'm having problems showing the other tabs submenus when I hover or click on the tabs. Any feedback is greatly appreciated.
