What do you mean by "dynamic"?
I mean that it should be created on the fly: If someone clicks on an element in the navigation-bar a list with all the sub-elements of this element opens under the element and the open subelement has a different color. E.g.:
1.This is my menu (now it showes only the elements)
-Welcome
-News
-Products
-Contact
- I click on "Products":
-Welcome
-News
-Products
--Internet Products
--Developement Tools
--Hardware
-Contact
Now the first sub-element of "Products", which is "Internet Products" is now opened in the content part of the page and displayed in a different color.
This example has only 2 hirachical-levels, but it should be possible to have as many levels, as I want.
Thanx for your help
