Q: I have implemented a deluxe-menu on my client's website and I had a couple of questions.
1. Can I control how fast the submenus scroll in my javascript menu examples? If you look at the site and hover over Need An Expert? on the menu and then point to Practice Areas, this submenu seems to scroll slower than if you mouse over "Technology" and scroll that submenu. The Technology submenu scrolls a lot faster. Is it because there are many more items in the Technology submenu? I tried to find a setting for "scroll speed" or the like, but I couldn't find it.
2. In internet explorer, when you mouse over Need An Expert?, Technology the first time you go to the page, there is a 3-4 second delay before the submenu opens. There are a lot of submenu items under Technology, but in Firefox, there doesn't seem to be this delay. Do you know why this would happen in IE? Is there a way to fix it? Could the problem be that each submenu item has a background graphic and this is causing the delay?
3. When you get to a page on the site and you rollover the top level menu, there is also a delay before the background image of the menu items shows up. You get a solid blue background color for a second or two (the bgcolor assigned) and then the graphic loads and shows up. Is there any way around this? I have a javascript to preload the image (back.jpg) but that doesn't seem to help.
Any help would be greatly appreciated!!!
A: 1. The scroll speed depends on number of items to be scrolled, more items -> faster scroll.
You can decrease the number of items or enlarge the size of submenu.
2,3. Please try to add the following param:
var dm_writeAll = 1;
It will load all backgrounds on page load, no on mouseover.
Q: First I want to thank you for the great support you provided. I have another question about the dynamic javascript tree. Is there a javascript API to fire an user click event so the browser will load proper page accordingly? I looked around the current APIs from your site and could not find one.
A: You can use dtreet_ext_userClick (itemID) function.
See more info:

Actually you can use your own Javascript code instead standard links and html code inside item text. For example:
var tmenuItems = [
["text", "javascript:your_code_here"]
];
or
var tmenuitems = [
["<div onClick='urlSubstitution(\'transco/sheet.asp?stype=1\')'>Table of Contents</div>", ""]
];
Q: I have a question, How can I open a new window of a specific dimension?
I Know how to use the “_blank” property to open a new window. But then how can I indicate the size of the new Window?
Can you please help me?
A: You should use a Javascript code with a link field so:
["Text", "javascript:window.open('../Help/Text_Index.htm', 'Help', 'height=450,width=600,scrollbars');"]
Try that.
Q: A lot of things have come in between... Just a few more Q's before I order.
1)
At the bottom of the page you refer to below, there is a table showing the tmenuItems array, itemInd and " submenuInd ". But in the examples on the same page, the function "dtreet_ext_getItemIDByIndex" takes the arguments (menuInd, itemInd). Is the argument "menuInd" the same as "submenuInd" referred to in the javascript menu design??
2)
When I highlight an item on "onload" I need to expand that item's parent(s), right? What will happen to other, already expanded nodes when I do that? Will they still be expanded or collapsed?
A: 1) menuInd is the index of a tree menu on a page, >= 0.
First menu - menuInd=0
Second menu - menuInd=1
Third menu - menuInd=2
Fourth menu - menuInd=3
...
2) Yes, the already expanded nodes will be expanded.
