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.

Q: I have used one of your products in the past, but bare with me as I am not a programmer. It was a Basic Horizontal Menu that I used mostly the defaults with.
I have a New website that needs to have more than one MENU....
1 - Header = (Horizontal) Drop down Menu
2 - Right Side Bar = (Vertical) MAIN Menu with sub-menus
3 - Lower Side Bar = (Vertical) Menu #2 with sub-menu
4 - Footer Menu = (Horizontal) Pop-up Menu?
I am not sure how this all would be accomplished on one page.
I have tried reading the INFO on the site but I get lost in all the data.
Could you explain a little better please?
A: You can add as many menus as you want on the one page.
You should call
<SCRIPT type=text/javascript> var dmWorkPath = "data.files/";</SCRIPT>
<SCRIPT src="data.files/dmenu.js" type=text/javascript></SCRIPT>
and then call your data files:
<SCRIPT src="data.files/data1.js" type=text/javascript></SCRIPT>
<SCRIPT src="data.files/data2.js" type=text/javascript></SCRIPT>
<SCRIPT src="data.files/data3.js" type=text/javascript></SCRIPT>
<SCRIPT src="data.files/data4.js" type=text/javascript></SCRIPT>
Q: I used the drop menu creator to create a simple tab example, and I created a simple HTML file to display the tabs. It initially appears fine when the page first displays (e.g., the correct div is hidden), but when I *first* click on a tab I always get a javascript error deep in the .js code. Then I click around a bit between the tabs and get some display problems (no more javascript errors though), until finally the show/hide logic recovers and all looks ok.
The error I initially get is something like “tabs[…].id is not an object”. I have the IE7 debugger turned on, otherwise I might not ever see this error.
FYI, I tried your example menus on your web site and everything is fine! Maybe the .js files on your web site are not the same as those created by the generator?
A: You should set the following parameter in drop menu creator:
var bselectedSmItem=0;
