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 haven’t had any problems using the drop line menu, until now when I had to make some changes. After adding some sub-menu items on two of the drop line menu buttons, those menu’s drop down upwards, instead of downwards like the rest. I tried deleting them and remaking them, but then the menu appeared to have no image behind it, only a colour. So I duplicated a working menu item, and then modified it to be what I wanted – and it still drop down upwards!
A: Please check the following drop line menu parameter:
var subMenuVAlign="top";
Q: I am programming in asp.net 1.1 and asp.net 2. I have a situation where the client wants to govern security with roles. Is there any functionality for deluxe tree to show/hide specific branches based on security levels (i.e. roles)?

Q: Is there any way through script to call the function that would be called if the user clicked a dhtml tabbed menu?
A: You're able to use Javascript for each item, for example:
var bmenuitems = [
["item text", "javascript:your_code_here"]
];
Unfortunately, you can't assign onmouseover/onClick event to each item.
However, you can achieve this by using standard html objects within items, for example:
var bmenuitems = [
["<div onClick='your_code_here'>item text</div>", "index.html"]
];
