Q: Compliments on your product, I particularly enjoy the complete set of gui and java, that allows for the quick changes.
After a couple of months of using the trial, I have now purchased it and installed the license.
My question however regards the performance of the menu. Using firebug I note that my deluxe menu .js are the performance bottlenecks, It appears as if they are not being cached and it appears that collecting them is taking longer then the other .js files. What can I do to optimize the load time of the javascript multi level menu and prevent, reloading it from the server with every page reload. The apache has set the expiry correct I believe, as I understand from the header.
A: You can try to use AJAX technology.
AJAX-like technology: data for submenus can be loaded "on-the-fly" from the server.
New parameter:
var tajax = 0/1; - disables/enables AJAX-like support
Current syntax for item parameters ( var tmenuItems):
[text, link, iconNormal, iconOver, iconExpanded, tip, target, itemStyleInd, itemXPStyleInd, jsFileName]
Where jsFileName - .js filename on the server with submenu items ( var tmenuItems).
Q: You've been helping me with some issues on the Deluxe Tree Menu system my company has purchased and most issues are resolved, so thank you! One big problem remains though and we can't seem to figure it out, so I hope you can help.
What we want is, when a user enters our site from the index (home) page then clicks on a link and the sub-page opens, for the dhtml menu tree to be open to the section the user is in and viewing. We also DO NOT want the browser to save the state of the menu, since that is inconsistent with where the user is in the site. Note: we do not use the Menu on the home page, is this a problem?
Per your tech support email, I've added the expand code, which works going from the home page to sub-pages. However, it interferes with navigating to other sub-pages once your in the site. The menu doesn't keep the section open, it closes back up. You mentioned the expand code has to be entered on every page....is that so in this instance and if so, that's a maintenance nightmare - does a better way exist for this type of menu?
Then we activated the "save state" option and the menu stays open on the sub-pages, but the expand option doesn't work.
It's like they cancel each other out and you can only have one or the other.
Can I get these two to work together? What do I need to do? Is it better to use the XP-style menu?
A: When user clicks the link, the browser loads a new page and the script re-create the dhtml menu tree.
If you want to open the needed section automatically on load you can use the following:
1. Save the state to cookies
2. Use frames
3. Put the special script on each page of site that will open appropriate section.

Q: I have a Menu called topnavbar.js when this menu is applied to a page not in a subfolder the links work. This topnavbar menu includes the following items; District Office, Cumberland Head Elementary School, Beekmantown Elementary School, Beekmantown Middle School, and Beekmantown High School.
However, if you put the topnavbar on a page that is located in a subfolder the links in the topnavbar add this subfolder name to the link. So instead of districtoffice.htm the link is transportation/districtoffice.htm and that page doesn’t exist.
A: You can use additional parameters to make menu paths absolute:
var pathPrefix_img = "http://domain.com/images/";
var pathPrefix_link = "http://domain.com/pages/";
These parameters allow to make images and links paths absolute.
For example:
var pathPrefix_img = "http://domain.com/images/";
var pathPrefix_link = "http://domain.com/pages/";
var menuItems = [
["text", "index.html", "icon1.gif", "icon2.gif"],
];
So, link path will be look so:
http://domain.com/pages/index.html
Images paths will be look so:
http://domain.com/images/icon1.gif
http://domain.com/images/icon2.gif
Please, try to use these parameters.
Q: > You should call the following function:
> dtreet_ext_getItemIDByIndex (0, 12)
> where 12 - is index of the item.
How would I know that 12 is the index of the item? How is itemInd different from its itemID? I assume the menuInd is always 0 for the first menu (or only in my case) menu on a page?
A: Yes, menuInd is the number of the menu on your page (in your casemenuInd=0).
itemInd is the number of the item in your menuItems, for example:
var tmenuItems =
[
["Home", "http://deluxe-tree.com", "icon1_t.gif", "icon1_to.gif","", "Home Page Tip","_blank"],//itemInd=0
["<img src='data_files/images/sep.gif' width=113 height=1>"],//itemInd=1
["+What's New<br><span id='letter'>This is pretty cool. I need to buy this deluxe menu</span>", "", "icon2_t.gif", "icon2_to.gif", "", "Product Info Tip"],//itemInd=2
