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: I am testing your product, and I would like to know, on the menu can the Plus sign be changed to expand a menu to a pointer or bullet?
A: You can use your own icons instead of Plus sign.
You should use the following parameters:
var texpandBtn=["default.files/expandbtn2.gif","default.files/expandbtn2.gif","default.files/collapsebtn2.gif"];
var texpandBtnW=9;
var texpandBtnH=9;
Q: Thank you for such an excellent product. I have a question pertaining to the submenu items in your tree-menu line. My menus are 540px wide and contain lots of text with good sized pictures (icons). Can I use an iframe tag inside of the css menu submenu instead of simple text with this icon?
A: You are able to paste any html code within items.
So you can paste a form too.
For example:
var menuItems = [
...
["||<nobr><FORM method=GET action='http://www.google.com/custom'><input name='as_q' value='search
the web' size=15 style='font-size:10'> <INPUT type=hidden name=cof
value='LW:144;L:http://domain.edu/images/sulogo.gif;LH:45;AH:center;GL:0;S:

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.
