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 want the background highlight stay on after the item is pressed in navigation bar script.
A: You can set a pressed item using Javascript API:
function dtreet_ext_setPressedItem (menuInd, itemID)
Please, see here:

You can also set
var tsaveState = 1;
More info you can find

To expand specific items you should use API function
function dtreet_ext_expandItem (itemID, expand)
Q: When I create a tab which has no sub-items, there is a white line drawn under the whole top javascript tabbed menu bar.
How do I avoid this?
A: Each menu item should have subitems (in the TabMode).
If you don't want to have subitems for some items you can add onesubitem and delete Item Text.
["Item 2","", "", "", "", "", "", "", "", ],
["|","", "", "", "", "", "0", "", "", ],
Q: Is it possible to insert an item at the top of the submenu in the html popup menu?
A: To insert item in the specific position you should use the following function:
function dm_ext_addItemPos (menuInd, submenuInd, iParams, Pos)
Adds the new item to a submenu.
menuInd - index of a menu on a page, >= 0.
submenuInd - index of a submenu, >= 0. See more info about indexes here.
iParams = [array] - the array of item parameters.
Pos - the position in the menu where you want to add new item.
