#4 Customize folder icons?

[Mike O'Reilly]

Hi: I've been experimenting with creating "open and close"
icons for folders in the Tree Menu, and I know how to
customize the code for the primary menu folders. For
example, I can create a main folder called "Bookstore" and
customize the "menu.makeLastSubmenu" like this:

menu.makeLastSubmenu(Var1,false, 'book-closed.gif','book-
open.gif');

Now when the menu appears, there will be a book-closed
icon that changes to a book-open icon when anyone clicks
on the + symbol. This information was included in the
downloaded source code examples.

So far, so good ... but now I can't figure out how to make
the same thing happen for a "folder in a folder". For
example, if I create a folder in the Bookstore folder
called "My New Book" (with the intention of adding links in
the new folder), I can't find the right place to add the 'book-
closed.gif','book-open.gif' and make the same cool thing
happen for that sub-folder. I know it's possible, because I
found a Tree Menu web site at http://www.tms.ws that has
2nd level open/close customized icons.

I did investigate the MTMIconList variable, but I think that
isn't the right place to make this happen. I'm looking for a
customizable solution - in fact, my "play site" is at
http://www.supportnexus.com if you want to look at my
progress to date.

Any help or advice you have for me would be greatly
appreciated.

Thanx
