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: I've looked through the FAQ's till my eyes burned... I know how to collapse/expand all on page load, but can't find an answer to this specific question
I am using tsaveState=1 and tcloseExpanded=1 and that works great when navigating the javascript vertical tree menu. But I'd like to be able to tell the javascript vertical tree menu to collapse all the way on the initial page load, without resetting those first two variables.
for instance;
a user logs on, goes to the order page, uses the menu to navigate and place an order. After the order is processed through a php verification page, the user is directed back to the order page via the php header() function, with the menu still intact, and the values of the order updated.
But once the user navigates away from the order page, and then returns to complete another order, I'd like the menu items to all be collapsed.
If that's not an inherent design of your menu program, is there a variable that I can pass with the initial load that will cause a full collapse?
A: No, unfortunately there is no such parameter in Deluxe Tree.
But you can try to delete
var tsaveState=1;
parameter from your data file and add it on your html page directly.
So, on your initial page you can set:
var tsaveState=0;
and on other pages you should set:
var tsaveState=1;Q: Can I ask a technical question? I am using the menu in a frameset, and I would like for the drop down menu selected branch to sty highlighted after the user moves the mouse to another window (where the menu brings up a new page), just so the user knows where he/she is. Is that possible?
A: But if you open links in the another frame (window) the initial frame with your menu isnot reloaded, so the clicked item will be highlighted.
You should set the following parameters:
var ttoggleMode=1;
var tpressedFontColor="#AAAAAA";
You can also set the following parameter to save menu state:
var tsaveState=1;
var tsavePrefix="menu1";
If you install the menu without frames. On your pages you should call the following function/functions to expand/highlight items, for example:
<script>
dtreet_ext_expandItem (dtreet_ext_getItemIDByIndex (0, 0), 1);
dtreet_ext_setPressedItem (0, dtreet_ext_getItemIDByIndex (0, 1));
</script>

For example, can your dhtml menu source code load the child of a node once the node is clicked on?
A: You can use AJAX like technology.
http://deluxe-menu.com/ajax-technology-menu-sample.html
You may generate a menu from a database or XML using any server-side script, e.g., PHP, ASP, VB, etc.
However, these scripts don't work inside of Javascript .js files, so, you should move parameters of a menu from a .js file into an html-page, e.g.:
<!-- Deluxe Menu -->
<noscript><a href="http://deluxe-menu.com">Javascript Menu by Deluxe-Menu.com</a></noscript>
<script type="text/javascript"> var dmWorkPath = "menudir/";</script>
<script type="text/javascript" src="menudir/dmenu.js"></script>
<!-- (c) 2006, http://deluxe-menu.com -->
<script type="text/javascript" language="JavaScript1.2">
// and describe parameters of a menu
var parameter1=value1;
var parameter2=value2;
etc.
var menuItems = [
// here you generate items using server-side scripts (php, asp, vb, etc.)
];
</script>
The example of the menu working with PHP/MYSQL you can find here:
