7. I need to have a tree within another element that uses scroll

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: Hi, I am testing your menu system for my company and would like to know how to keep the menu in the centre of the page like <centre></centre>.
I know how to do it without a floating menu but cannot work out how to do this with it floating.
A: When you use floatable menu you can't use relative menu position.
So, if you use
var absolutePos = 0;
and to center the menu you use <p> or <div> with the center alignment your menu won't float.
To center your floatable menu you should set absolute coordinates.
