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: We have been using a free javascript for a couple of years but now we would like to have a functionality that our existing js is missing.
Basically, we need the ordinary tree view javascript with "+" and "-" that highlights the node clicked. No problem with that I suppose... BUT, we have a bunch of pages with internal links, linking the visitor to other pages within the site (i.e. they don't have to use the leftside tree navigation). What I want is that the navigation js recognizes that a page loads without any node has been clicked, and automagically expands the nav tree and highlights the node for that page.
No AJAX, no XML, no php or asp, just plain HTML + JS is a requirement from our customers.
Is that possible with any of your products...?
A: Yes it is possible with Deluxe Tree.

A: We have the following API function to highlight the pressed item in Deluxe Tree
function dtreet_ext_setPressedItem (menuInd, itemID)
But unfortunately this function doesn't work for AJAX submenus.
We'll try to add this feature soon (using save state feature).Q: I have a popup that in one of the submenus has an input field.
There is a problem – if the user clicks into the entry field,
but moves the mouse outside the php dhtml menu,
the menu can close while the user is still typing.
Is there any way to prevent that from happening?
A: You can make submenus to stay visible till you click outside the menu or scroll your page.
To enable this feature you should set the following parameter:
var smHidePause=-1;
