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.

Demo:

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{
display: list-item;
float: none;
}

/*All subsequent sub menu levels offset after 1st level sub menu */
.suckertreemenu ul li ul li ul{ 
left: 159px; /* no need to change, as true value set by script */
top: 0;
}

/* Sub level menu links style */
.suckertreemenu ul li ul li a{
display: block;
width: 160px; /*width of sub menu levels*/
color: navy;
text-decoration: none;
padding: 1px 5px;
border: 1px solid #ccc;
}

.suckertreemenu ul li a:hover{

}

/*Background image for top level menu list links */
.suckertreemenu .mainfoldericon{
background: #F3F3F3 url(media/arrow-down.gif) no-repeat center right;
}

/*Background image for subsequent level menu list links */
.suckertreemenu .subfoldericon{
background: #F3F3F3 url(media/arrow-right.gif) no-repeat center right;
}

* html p#iepara{ /*For a paragraph (if any) that immediately follows suckertree menu, add 1em top spacing between the two in IE*/
padding-top: 1em;
}
	
/* Holly Hack for IE \*/

Hey, thanks man. Jchalos it helped much to me, because i am making one web page, that i need to complete ASAP, and i am using this tree menu script. Thanks.

I found this menu is useful for my project

I am using the menu above an embedded Flash movie. It seems to work alright in Safari and Firefox but not in IE PC. The menu seems to open behind the Flash movie on the PC. Is there anything I can do?

I have the same problem - in IE submenu disappears when trying to go down in menu.. How can I fix this ? Help !

Hi all

I'm really pleased with this menu, have a look at the link, I've been able to modify it to a very individual look. (Well I think so...)

BUT...

How would you go about having multiple menus on a page?

How would you get it to respond to seperate css?

Regards

Dave

PS - A trick for getting the menu to get the Z-Index to work in IE 6&7:

.suckertreemenu ul{
margin: 0;
padding: 0;
list-style-type: none;
font-size: small;
font-style: normal;
z-index: 50;
position: relative; /* This causes the Z-Index to work correctly in IE6&7 */
}

Hi... Right I've started to try and get to grips with this..

I would like to have both a horizontal and a vertical menus on the same page...

It would seem that the two sets of JavaScript do not coexist on the same page.

The Vertical seems to be dominant and as soon as its added it seems to stop the horizontal menu from working.

I'm not a JavaScript programmer (Yet...?!?!)

Is it possible to have both Horzontal and Vertial Menus coexting on the same page?

Thanks

Dave

OK.. Done It...

simply change the "var menuids" id's to be different so I made one "var menuid":

var menuids=["treemenu1"] //Enter id(s) of SuckerTree UL menus, separated by commas

var menuid=["suckerfish1"] //Enter id(s) of SuckerTree UL menus, separated by commas

If you follow...

Regards

Dave

I like this menu but the sub menu is hidden when you bring the mouse over one of these gaps. Any help is appreciated. I am using Winvisita Ie7
