I need a left side dynamic menu

Hi All,

I am in need for a menu for my website.
It needs to be a left side menu something like as mentioned below:

-----------------
Header 1
--> Sub heading 1a
--> Sub heading 1b
--> Sub heading 1c
Header 2
--> Sub heading 2a
--> Sub heading 2c
..
..
..
Header 999
--> Sub heading 999a
--> Sub heading 999b
-----------------

My need is that i need to be able to add more headers and sub headings in future. Also, header and subheading needs to be a link.

Please help me out with this. I did try some of the menus in various websites. but none seems to be user friendly. I don't want to edit every html page for menus.

Example: This website can be a good example [Structure wise]
http://www.celextel.org/home.html

But then menus don't close here, which is a problem. It would lead me to scroll down to see, which is the next header!!!!!

I did try
http://www.dynamicdrive.com/dynamici...bar2/index.htm

but then, first one wants me to add a button!!! for every link!!! and it doesn't allow to add a big list of headers.

*** Please help me out with this problem *****
