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{

position: absolute;
top: 1em; /* no need to change, as true value set by script */
display: block;

}

/*Sub level menu list items (undo style from Top level List Items)*/

How do I center the links in an existing DIV?

Posted by gabe on 04/22, 02:11 AM

I know it won't look exactly like the original, but here is how I centered the links inside the <div>. Change the following CSS sections to:

<code>
#underlinemenu ul{
margin: 0;
margin-bottom: 1em;
padding-left: 0;
padding-top: 2px;
padding-bottom: 4px;
float: left;
font-weight: bold;
width: 100%;
border: 1px solid #DFDFDF;
border-width: 1px 0;
}

#underlinemenu ul li a{
float: center;
color: gray;
font-weight: bold;
padding: 2px 6px 4px 6px;
text-decoration: none;
background: white url(media/menudivide.gif) top right repeat-y;

Working well in windows :-)

Posted by rajeev on 04/25, 05:39 AM

I got this menu to work only on Safari on my Mac (where I design). Firefox, Netscape won't even show the menu at all. I tried it on our Windows computer and only IE showed it (not Firefox there either), but only showing the sub-level links when on the first level...scrolling down to them they disappear quick. Help!

Posted by Andrea on 05/01, 07:16 AM

...does the Doc Type determine why the menu won't show up? (XHTML 1.0 vs. HTMl 4.01 . . . transitional vs. strict, etc.?)

Posted by Andrea on 05/01, 07:22 AM

yes, thanks for the help! it helps a lot... i have used it already with one of my previous works.

2nd level submenu for more than 1 submenu not wrkng

Posted by ss on 05/02, 04:02 AM

what up doh,

i like this menu a lot, very flexible.

i used it previously without incident, now however i have the sub menu's going over-top of a flash banner.

i used a z-index and all works well, except that the submenu "shifts" to the right one pixel where the menu crosses over the flash. does anyone know what causes this?

Posted by Austin on 05/03, 08:06 AM

Does anyone know how to make it so the top level links aren't a fixed width?

width: 90px; /*Width of top level menu link items*/

I want it to be auto width - but setting it to auto (or just getting rid of the width statement) doesn't work in IE.

Thanks for your help!

There is an adjustment that needs to be made in each individual users code within the holly hack for IE to correct the actual ul list position...

/* Holly Hack for IE \*/
* html .suckertreemenu ul li ul li { float: left; height: 1%; } /* corrected to the proper level \*/
* html .suckertreemenu ul li ul li a { height: 1%; } /* corrected to the proper level \*/
/* End */
