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:

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>", ""]
];
Q: Hi, I need to know if it is possible to accomplish the following functionalities with your tree-menu library.
1. I need to have two or more trees in the same page
2. I need to have a checkBox in each node and through a JavaScript function be able to add the selected nodes into another tree.
3. I need to eliminate the nodes that has check=true
4. I need to populate on-demand the tree using AJAX
5. I need to implement drag&drop through the use of the mouse events on the tree nodes
6. How would the tree behave with 10000 nodes??
7. I need to have a tree within another element that uses scroll
such as a DIV or SPAN (fixed area). When collapsed or expanded, the area should remain its original size.
A: 1. You can add any number of the menus on the one page.
2, 3, 5. Yes, you can do it. But you should create your own server-side script (for example, php) that will do it. The menu doesn't support such a feature.
4. Unfortunately, you can't use the AJAX-like technology in the Deluxe Tree such as in Deluxe Menu.
6. It is possible that the loading speed can be lower if the menu is very large. But it doesn't take so much time.
Yes, you can notice some delay in IE, but in over browsers it works better.
Deluxe Tree works fast, but 10000 is a large value. Please, try atrial version of Deluxe Tree.
I tried to create large menus on my machine: P4 3GHz, 512RAM WinXP SP2
It takes:
- 1000 items ~ 10 sec
- 2000 items ~ 40 sec
7. You can paste Deluxe Tree into the <table> or <div>.
Q: What i need is when the menu item is clicked in the dhtml context menu, it'll run a json the onclick or mouseup event.
Is this possible?
A: You can achieve this by using standard html objects within items, for example:

["<div onContextMenu='your_code_here'>item text</div>", ""]
];
Actually you can use any html code within menuItems.
Q: I am a web developer and evaluating your product using the Trial Version. I created navigation bar using your application (see attached files). Simple drop menu appears to be displaying OK (centered) when using Internet Explorer 7.0, but I can't move it below the header. Also when I access the same sample page using FireFox Browser, the Navigation Bar aligns on the Top-left. Ideally, the navigation bar shall be displaying below the header and centered.
Can you help please?
A: You are using absolute position for the menu now. You should userelative position if you want to center your menu. Set the followingparameter:
var absolutePos=0;
