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:

- 2000 items ~ 40 sec
7. You can paste Deluxe Tree into the <table> or <div>.
Q: Many internet cafe's don't have JavaScript installed. Is there a way to show a link to an alternative page if there is no JavaScript installed on the computer?
A: Your visitors should change security settings in IE to allow Javascript on pages they load.
When your security settings in IE doesn't allow Javascript onpages you load you can't see a dynamic page content.
There is no way to enable these preferences automatically, in othercase there are no reasons to create security preferences.
Q: It's been couple of months since I last time asked something about tree menu. I am still evaluating the software.
I have a short question. Is it possible to use CSS instead of JavaScript to tune the look and feel of the tree menu? For example I would be interested in giving menu css java item height value in relative numbers (em or %) rather than specifying a size in pixels...
A: But actually you can use 'em' and '%' units in Deluxe Tree, forexample.
var tmenuWidth="13em";
var tmenuHeight="12em";
var tmenuWidth="35%";
var tmenuHeight="15em";
