Original call would look something like this, where entryID is all you need to
start with:
cfset myReplyTreeQry = getChildren(url.entryID, request.datasource)
This would create a query result called myReplyTreeQry with the following
columns:
entryID
replyID (of each reply)
Thank you very much - this works beautifully!

There are loads and loads of DHTML menus out there, e.g.
http://www.dynamicdrive.com/dynamicindex1/hvmenu/
with the actual menu code taken care of, all you have to do is recurse over
your database and write out the menu items.
last time i checked, cftree outputs a java applet, not javascript.
Depending on your DB you may be able to do the recursion there rather
than in the CF or JS code:

An easy way to do recursion in cf is to use a custom tag. One of the
things you will have to do is have your top level be set to a parent
id that wont get used in any levels below it. I like to set the top
level to zero or one.
The first time you call your custom tag you just pass the top

In a CF page, all variables on that page (and cfinclude'd pages) have the
