Q: Do you have a template example of creating menu javascripts using data stored in a database?
A: You may generate a menu from a database or XML using any server-side script, e.g., PHP, ASP, VB, etc.
However, these scripts don't work inside of Javascript .js files,
so, you should move parameters of a menu from a .js file into an html-page, e.g.:
<!-- JavaScript Tree Menu -->
<noscript><a href="http://deluxe-menu.com">Javascript Menu by Deluxe-Menu.com</a></noscript>
<script type="text/javascript"> var dmWorkPath = "menudir/";</script>
<script type="text/javascript" src="menudir/dmenu.js"></script>
<!-- (c) 2006, http://deluxe-menu.com -->
<script type="text/javascript" language="JavaScript1.2">
// and describe parameters of a menu
var parameter1=value1;
var parameter2=value2;
etc.
var menuItems = [
// here you generate items using server-side scripts (php, asp, vb, etc.)
];
</script>
The example of the menu working with PHP/MYSQL you can find here:
http://deluxe-menu.com/rq-loading-bar-MySQL-support.htmlQ: I have small problems with your javascript menu system.
#1. I am creating a multi-level menu, am I limited to a gird format or can every item have a variable column width?
#2. With submenus, I want to have the submenu be the same width as the parent cell, is there a simple command for this, or do I have to guess the column widths until it fits correctly?
#3. In those same submenus, I have items that are longer than the parent, is there a word wrap or a way to define a break, rather than having the scroll feature?
A: 1) You should use Individual Item Styles.
For example:
var itemStyles = [
["itemWidth=120","itemBorderWidth=1","itemBorderStyle=solid,solid","itemBackColor=#ACF88B,#ACF88B","itemBorderColor=#329309,#329309"], //style0
["itemWidth=100","itemBorderWidth=1","itemBorderStyle=solid,solid","itemBackColor=#FFFFFF,#FFFFFF","itemBorderColor=#1B92E9,#1B92E9"], //style1
["itemWidth=130","itemBorderWidth=1","itemBorderStyle=solid,solid","itemBackColor=#FF9684,#FF9684","itemBorderColor=#EC7575,#EC7575"], //style2
["itemWidth=150","itemBorderWidth=1","itemBorderStyle=solid,solid","itemBackColor=#84F9FF,#84F9FF","itemBorderColor=#00B8C1,#00B8C1"], //style3
];
var menuStyles = [
["smColumns=2"], //style0
];
["Home","testlink.htm"],
["Samples","testlink.htm"],
["|Group 1","", , , , , "0", , , ],
["|Group 2","", , , , , "1", , , ],
["|Group 3","", , , , , "2", , , ],
...
[" More Samples","testlink.htm"],
["|Group 1","", , , , , "3", "0", , ],
["|Group 2","", , , , , "1", , , ],
Where "0", "1", "2", "3" - style number in itemStyles.
2) You can also use Individual Item Styles.
var itemStyles = [
["itemWidth=120px"],
];
var menuStyles = [
["smWidth=120px"],
];
["Product Info","", "default.files/icon1.gif", "default.files/icon1o.gif", , , "0", , , ], // itemStyles
["|Features","testlink.html", "default.files/icon2.gif", "default.files/icon2o.gif", , , , "0", , ],
["|Installation","", "default.files/icon2.gif", "default.files/icon2o.gif", , , , , , ], // menuStyles
3) Try to set this parameter:
var noWrap=0;
Q: Why is the submenu a different colour has a different colour than menu items - surely that's not an IE specific feature? The top-level menu items seem to be a different size too, so the layout in IE looks more even.
A: Submenus has a different color because they have a transparency:
var transparency="90";
Set it to 100.
Submenus also have larger width than top items because they containsmore text. If you want to wrap the text, use
tag between item words.
Q: Thank you for your prompt replay- the menu now works! However, the multi level dhtml menu takes forever to load up as demonstrated on our website. I was wondering whether there was any possible way of getting it to load up faster.
A: I have noticed no delays in the menu loading.
But your menu is big enough. You can try to us AJAX technology.

Try to set the following parameter also:
var dm_writeAll=1;
