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.

http://deluxe-tree.com/highlight-selected-menu-item-sample.htmlQ: 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 to know how I can set a menu item to pressed
when a page is loaded in javascript drop down menus.
A: You should set a pressed item using Javascript API:
function dm_ext_setPressedItem (menuInd, submenuInd, itemInd, recursion)
Sets a current pressed item.
menuInd - index of a menu on a page, >= 0.
submenuInd - index of a submenu, >= 0.
itemInd - index of an item, >=0.
recursion = true/false - highlight parent items.
Q: Comprehensive Mental Health has a site license to \use Deluxe Menu. We are currentlyrunning version 2.0.
Unless we set the topdy parameter to be -65, our submenus do not appear adjacent to the toplevel menu. Below are our parameters and our menu. What is causing this problem?
A: It is possible that you have some problems with your css.
The problem is that the script can't get css properties of the object if they are described in separate .css block (or file).
In other words, you can't get the value of "position" attribute of the object if the object doesn't have this property within inline style(style="position:absolute"). To get the value you should move .css style into style="" attribute.
Please, try to add your
css file -> inline css, for example:
You should add <DIV id=SiteMenu>
to the
style="position:absolute;"
So, you'll have:
<DIV id=SiteMenu style="position:absolute;">
Check that.
