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: In javascriptcoding I have id of the submenu. How can retrieve id of the parent menu item in the drop-down menus?
A: You can try to use the following function
function dm_ext_getSubmenuParams (menuInd, submenuInd)
Returns submenu parameters in the array:
[submenu_id, items_count, parent_item_id, submenu_level, is_horizontal]
menuInd - index of a menu on a page, >= 0.
submenuInd - index of a submenu, >= 0.
Using this function you can retrieve the parent_item_id.

Q: There is a default gap between two collapsible javascript menu buttons. Suppose the two menu are "Company profile" and "Service", there is a default gap between those tow , it is not taking the specified space( for example I am putting 2px gap but it is taking a default gap) Please suggest me the solution for the same.
A: You should use new parameter in the data file:
var tXPMenuSpace=0;
Q: I have heard from some page visitors, that they couldn’t see the menu. Could this be a problem with deactivated Java script or could you tell me some possibilities what it could be.
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.
