This is a code that I use to dynamically create the drop down menus. First, you have to edit the following code and put it in your Javascript. Notice : /*** SET BUTTON'S FOLDER HERE ***/. Edit that to your folder. Also, the /*** SET BUTTONS' FILENAMES HERE ***/. This creates a mouseover when the drop down is activated. Put all your onmouseover images under: oversources = new array; and your onmouseout images under : upsources. Be sure to set your on and out images above each other.
CODE
/*** SET BUTTON'S FOLDER HERE ***/
var buttonFolder = "img/";
/*** SET BUTTONS' FILENAMES HERE ***/
upSources = new Array("image_out.gif","image_out.gif","image_out.gif","image_out.gif","image_out.gif");
overSources = new Array("image_on.gif","image_on.gif","image_on.gif","image_on.gif","image_on.gif");
// SUB MENUS DECLARATION, YOU DONT NEED TO EDIT THIS
subInfo = new Array();
subInfo[1] = new Array();
subInfo[2] = new Array();
subInfo[3] = new Array();
subInfo[4] = new Array();
subInfo[5] = new Array();
//*** SET SUB MENUS TEXT LINKS AND TARGETS HERE ***//
subInfo[1][1] = new Array("new","new.html","");
subInfo[1][2] = new Array("new","new.html","");

// HIDE ONE SUB MENU
function hideSubMenu(subID) {
if ( overSub == false ) {
moveObjectTo(subID,-500, -500);
}
}
//preload();
Creating your drop down options
Now, to create the your options simply edit the subinfo array. Notice that this is button 1 and has 4 menu options.
CODE
//*** SET SUB MENUS TEXT LINKS AND TARGETS HERE ***//
subInfo[1][1] = new Array("new","new.html","");
subInfo[1][2] = new Array("new","new.html","");
subInfo[1][3] = new Array("new","new.html","");
subInfo[1][4] = new Array("new","new.html","");
CSS
In CSS is where you create how the menu looks. You can edit the color of the background, border, ...ect. This menu will overlap anyother information underneathe the menu. I like to give it a little bit of transparency.
CODE
filter: alpha(opacity=75)
CODE
.dropmenu {
position: absolute;
left: -1500px;
visibility: visible;
z-index: 101;
float: right;
width: 150px;
filter: alpha(opacity=85);
border-width: 4px;
border-style: outset;
border-color: #888888;
background-color: #333333;
}
.dropmenu ul {
margin: 0;
padding: 2;
list-style-type: none;
}
.dropmenu li {
display: inline;
}
.dropmenu a, .dropmenu a:visited, .dropmenu a:active {
display: block;
width: 150px;
padding: 2px;
margin: 1px;
font-family: Verdana;
font-size: 10px;
font-weight: normal;
text-align: left;
text-decoration: none;
color: #FFFFFF;
background-color: #6282FA;
}
.dropmenu a:hover {
padding: 2px;
margin: 1px;
font-family: Verdana;
font-size: 10px;
font-weight: normal;
text-align: left;
text-decoration: none;
color: #0012ff;
background-color: #EDA031;
}
If you have trouble witht the drop down being off set, set the margins wider.
