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 Javascript/DHTML Tree such as in JavaScript Tree 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.
Javascript/DHTML Tree works fast, but 10000 is a large value. Please, try atrial version of Javascript/DHTML 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 Javascript/DHTML Tree into the <table> or <div>.
Q: Why don't any of the effects work in Firefox? I have built several different types of menus and they don't work the same in firefox as they do in IE. Is there a way to fix this? i.e. adding any html code or anything?
A: Yes, it is really so. Firefox supports only transparency of the menu.
Visual effects work in IE only. other browsers don't support them.

Q: Is there a way to hide a menu options using either CSS or the java api based on the site user for the mouseover menu?
A: JavaScript Tree Menu supports Javascript API.
You can find more info here:
http://deluxe-menu.com/dynamic-functions-sample.html
You can try to use API functions in that case:
function dm_ext_changeItemVisibility (menuInd, submenuInd, itemInd, visibility)
To disable items you should set the target parameter to "_".
You can try to use the following function
function disable() {
dm_ext_changeItem(0, 1, 1, ["", "", "", "", "", "_"]);
}
to disable your items.
Q: Is there a different type of menu, other than the way I have it set up, such as the tree type, that might load faster or take up less space when the page loads?
A: You should set
var dmAJAX=1;
create .js files with your submenus and call this files from your mainfile, for example:
var menuItems = [
["Home","testlink.htm"],
["Product Info","", , , , , , , "data-samples/data-ajax2.js", ],
["Samples","", , , , , , , "data-samples/data-ajax3.js", ],
["Purchase","testlink.htm"],
["Contact Us","testlink.htm"],
];
/*** data-ajax2.js ****/
var menuItems = [
["Features","testlink.htm"],
["Installation",""],
["Parameters Info","testlink.htm"],
["Dynamic Functions","testlink.htm"],
["Supported Browsers",""],
];
Add dmenu_ajax.js file in the same folder with your dmenu.js file.
Try that.
