Q: Compliments on your product, I particularly enjoy the complete set of gui and java, that allows for the quick changes.
After a couple of months of using the trial, I have now purchased it and installed the license.
My question however regards the performance of the menu. Using firebug I note that my deluxe menu .js are the performance bottlenecks, It appears as if they are not being cached and it appears that collecting them is taking longer then the other .js files. What can I do to optimize the load time of the javascript multi level menu and prevent, reloading it from the server with every page reload. The apache has set the expiry correct I believe, as I understand from the header.
A: You can try to use AJAX technology.
AJAX-like technology: data for submenus can be loaded "on-the-fly" from the server.
New parameter:
var tajax = 0/1; - disables/enables AJAX-like support
Current syntax for item parameters ( var tmenuItems):
[text, link, iconNormal, iconOver, iconExpanded, tip, target, itemStyleInd, itemXPStyleInd, jsFileName]
Where jsFileName - .js filename on the server with submenu items ( var tmenuItems).
Q: How I can write the changed dhtml pull down menu into a database?
A: Unfortunately, we don't have such example.
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.:
<!-- Deluxe Tree -->
<noscript><a href="http://deluxe-tree.com">Javascript Tree Menu by Deluxe-Tree.com</a></noscript>
<script type="text/javascript" src="menudir/dtree.js"></script>
<!-- (c) 2006, http://deluxe-tree.com -->
<script type="text/javascript" language="JavaScript1.2">
// and describe parameters of a menu
var parameter1=value1;
var parameter2=value2;
etc.
var tmenuItems = [
// 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:

This example is not for Deluxe Tree menu, but you can create your menu in the same way.
Q: You have been great help, but this will not work for me. All I want is the dropdown menu javascript I have attached to have these colors on the seperate top items. I just cannot make the software work . As soon as I get this done I promise to leave you alone

A: You should create 6 Individual Styles and assign them to you topitems.
var itemStyles = [
["itemBackColor=#0000ff,#0000ff","showByClick=0"], //style 0
["itemBackColor=#FF00FF,#FF00FF","showByClick=0"], //style 1
["itemBackColor=#00ffff,#00ffff","showByClick=0"], //style 2
["itemBackColor=#00ff00,#00ff00","showByClick=0"], //style 3
["itemBackColor=#FFFF00,#FFFF00","showByClick=0"], //style 4
["itemBackColor=#FF0000,#FF0000","showByClick=0"], //style 5
];
["Find out Who we are","http://www.humanscience.org/", "", "", "", "", "0", "0", "", "", "", ], //style 0
["Apply For Fellowship","http://www.humanscience.org/infoSnippets.cfm", "", "", "", "_blank", "1", "", "", "", "", ], //style 1
["Fellows Corner","", "", "", "", "", "2", "", "", "", "", ], //style 2
["Enroll in a course","", "", "", "", "", "3", "", "", "", "", ], //style 3
["Engage in a discussion","", "", "", "", "", "4", "", "", "", "", ], //style 4
["Read The Bulletin","", "", "", "", "", "5", "", "", "", "", ], //style 5
You can also set
var itemSpacing=0;
to delete spacing around the dropdown menu javascript.
Q: Is there a javascript API for the expandable menu tree to fire an user click event so the browser will load proper page accordingly? I looked around the current APIs from your site and could not find one.
Please advise.
A: You can use dtreet_ext_userClick (itemID) function.
See more info:
http://deluxe-tree.com/functions-info.html
Actually you can use your own Javascript code instead standard links and html code inside item text. For example:
var tmenuItems = [
["text", "javascript:your_code_here"]
];
or
var tmenuitems = [
["<div onClick='urlSubstitution(\'transco/sheet.asp?stype=1\')'>Table of Contents</div>", ""]
];
