Q: The value of dmAJAXCount = 0 (we don't set that parameter).
How exactly does this parameter work? When does it have to be set?

If you don't know exact number of submenus you can set a big value forthis parameter.
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: Do you have a menu that allows the sub-items to 'slide' out from the menu?
For example, you mouse-over the first button, and the sub menu slides from 'underneath' the button from left to right?
A: You should to use transitional effects.
Try to set
var transition=6;
var transOptions="";
var transDuration=350;
var transDuration2=200;
But notice that transitional effects are features of Internet Explorer5.5+ only.

Try that.
Q: The only remaining problem I see is that the html popup menu appears in slightly different positions depending upon where your mouse touches the icon.
Is there a way to make the menu position absolute in respect to the icon? I have tried playing with the menu item parameters that seemed related with no success.
A: See dm_popup() function parameters:
return dm_popup(menuInd, pause, event, x, y)
menuInd - index of the menu on a page, >= 0.
pause - determines the time when the html popup menu will be hidden.
event - constant. Do not change.
x, y - optional. Set these parameters if you want the menu to appear in the specified place.
In other case the menu will be shown in the mouse position.
