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: I would like to have the dhtml sliding menu save the state when reloading or refreshing the browser.Can this be done with the expandable menu? If so, what is the syntax?
A: You should use the following parameter:
var tsaveState = 1;
Example, you can find here:

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: We want to create a hyperlink (lets say google.com) to the item (eg. Industry,International Airlines etc) and display it in the dataframe.
For eg On clicking the 'International Airlines', the hyperlinked content should be displayed on the DataFrame along with expanding the navigation items. Right now it just expands the navigation , but the link doesn't work.
The hyperlink works fine for the subitems. We want to do the same for the main items as well.
A: You can write your top items in the following way:
["<a href='http://google.com' target='DataFrame' style='color: #000; text-decoration: none;'>International Airlines</a>","", "", "", "", "","DataFrame", "", "", ],
