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: Can you provide an example of how to dynamically change the menu items at runtime for the dropdown menus?
(asp is fine, but if it needs to javascript that is also ok)
A: 1) You can use API functions to affect items dynamically:
http://deluxe-menu.com/functions-info.html
2)Generate your menu items dynamically from database.
Unfortunately we don't have working example with ASP.
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 Menu -->
<noscript><a href="http://deluxe-menu.com">Javascript Menu by Deluxe-Menu.com</a></noscript>
<script type="text/javascript" src="menudir/dmenu.js"></script>
<!-- (c) 2008, 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:

Q: On the left menuline under the a1 link, shall appear the javascript menu div, but after several refreshes, nothing happens.
On the local computer, the javascript menu div is working perfectly!
Can you send me instructions, why this problem appears?
A: You've placed the javascript menu div in
<TD class=sidebar vAlign=top width=160>
tag with the following styles:
.sidebar TR {
DISPLAY: none! important
}
TD.sidebar IMG {
DISPLAY: none
}
.sidebar TABLE TR TD IMG {
DISPLAY: none
}
.sidebar TABLE TR TD {
DISPLAY: none}
That's why you cannot see the javascript menu div. Delete "DISPLAY: none" propertyfrom the style.
Q: I have been using the DHTML Menu program for years and they are working good.
But I found an office where the javascript tree menu example just simply does'nt appear.
I am curious about it, why just in that office the Menu is not working.
I can note than other javascript routines I put on my page are not working neither.
Can you give me some idea of what can I check on the computers?
Something on the explorer? (IE6) , or a kind of program?
A: Your browser has JavaScript option disabled.
It means that no one JavaScript element can be run.
You should to enable JavaScript in IE:
Tools -> Internet Options -> Security -> Custom level... -> Scripting -> Active Scripting = Enable
There is no way to enable these preferences automatically, in othercase there are no reasons to create security preferences.
You can use search engine friendly code, so you'll see all yourlinks (for the main items and submenus) when your security settings in IE doesn't allow Javascript.
You can generate search engine friendly code.
Deluxe Menu is a search engine friendly menu since v1.12.
To create a search engine friendly menu you should add additional html code within your html page:
<div id="dmlinks">
<a href="http://deluxe-menu.com">menu_item_text1</a>
<a href="http://deluxe-tree.com">menu_item_text2</a>
...etc.
</div>
To generate such a code use Deluxe Tuner application.
You can find this GUI in the trial package.
Run Tuner, load your menu and click Tools/Generate SE-friendly Code (F3).
