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 two bullet images used:

The CSS:

<style type="text/css">

.suckertreemenu ul{
margin: 0;
padding: 0;
list-style-type: none;
}

/*Top level list items*/
.suckertreemenu ul li{
position: relative;
display: inline;
float: left;
background-color: #F3F3F3; /*overall menu background color*/
}

/*Top level menu link items style*/
.suckertreemenu ul li a{
display: block;
width: 90px; /*Width of top level menu link items*/
padding: 1px 8px;
border: 1px solid black;
border-left-width: 0;
text-decoration: none;
color: navy;
}
	
/*1st sub level menu*/
.suckertreemenu ul li ul{
left: 0;
position: absolute;
top: 1em; /* no need to change, as true value set by script */
display: block;
visibility: hidden;
}

/*Sub level menu list items (undo style from Top level List Items)*/
.suckertreemenu ul li ul li{

It doesn't work properly in IE6 or 7 for me. If i move my cursor down the submenu, all the submenu expand till the end of the page. In firefox its perfectly alright.

Also can someone help me in making this menu right aligned I want this to align right on my webpage.

for all those who are having problems with this fantastic script, i have a solution if under ie 5,6,7 your sub menu items aren't selectable e.g. disappear when you roll over them etc.. then all you have to do is copy the javascript and css from the pages source this will fix your problem... i hope this helps others as this issue had me perplexed for ages...

peace

"copy the javascript and css from the pages source..." - what do you mean, keep it all in external files?

Posted by Ryan on 11/23, 08:25 AM

Hi,
I used the css code and the html code and it worked perfectly. If i have a table under the menu it works perfectly but if i have a container div under the menu it disapears behind the container div and is unselectable. What´s the problem? I tried with z-index but it doesn´t work. Does anyone know about this?
Thanks in advance

Anything on the bug in ie7 when moving over items too fast?

Has anyone figured out how to fix this?

Challenge Question:
How this manu can be CENTER Align? It always appear as left align.

Posted by Center Align Only on 11/28, 02:28 PM

@Center Align:

Put it in a div and center align the div.

Posted by J on 11/28, 04:16 PM

I already tested it. Center Align does not work with DIV. Actually, it center align the text of menu, not menu.

Beautiful

Google center aligning a div then, because it isnt a problem with the menu.

On a more important note, IE7 fast movement bug.

It seems that the problem does not appear when you have a few submenus in a row. However, the menu item 2 items down from the sub menu does experience the bug.

Any ideas?
