Using CFTREE to show recursive relationships

I'm struggling to expose a hierarchical query as a tree view in ColdFusion. I just can't figure out the mechanics.
Initially I want to expose it without a bind to a cfc. Then I want to expose it with a bind to a cfc so I can take advantage of the complete tree not loading until it is clicked.

Here is what the first level needs to be exposed as:

When you open all the levels:

Here a sample table which ties the parent and children together.

CREATE TABLE mycurric
    (parent_cd_crs                  VARCHAR2(30 BYTE),
    child_cd_crs                   VARCHAR2(30 BYTE))
/
INSERT INTO mycurric (CURRIC_CD_CRS,CHILD_CD_CRS) 
VALUES('MASTERCU','CRSA');
INSERT INTO mycurric (CURRIC_CD_CRS,CHILD_CD_CRS) 
VALUES('MASTERCU','LEVEL1ACU');
INSERT INTO mycurric (CURRIC_CD_CRS,CHILD_CD_CRS) 
VALUES('MASTERCU','LEVEL1BCU');
INSERT INTO mycurric (CURRIC_CD_CRS,CHILD_CD_CRS) 
VALUES('MASTERCU','LEVEL1CCU');
INSERT INTO mycurric (CURRIC_CD_CRS,CHILD_CD_CRS) 
VALUES('LEVEL1ACU','CRSB');
INSERT INTO mycurric (CURRIC_CD_CRS,CHILD_CD_CRS) 
VALUES('LEVEL1ACU','CRSC');
INSERT INTO mycurric (CURRIC_CD_CRS,CHILD_CD_CRS) 
VALUES('LEVEL1ACU','CRSD');
INSERT INTO mycurric (CURRIC_CD_CRS,CHILD_CD_CRS) 
VALUES('LEVEL1ACU','CRSE');
INSERT INTO mycurric (CURRIC_CD_CRS,CHILD_CD_CRS) 
VALUES('LEVEL1BCU','LEVEL2ACU');
INSERT INTO mycurric (CURRIC_CD_CRS,CHILD_CD_CRS) 
VALUES('LEVEL1BCU','LEVEL2BCU');
INSERT INTO mycurric (CURRIC_CD_CRS,CHILD_CD_CRS) 
VALUES('LEVEL1BCU','LEVEL2CCU');
INSERT INTO mycurric (CURRIC_CD_CRS,CHILD_CD_CRS) 
VALUES('LEVEL1CCU','CRSC');
INSERT INTO mycurric (CURRIC_CD_CRS,CHILD_CD_CRS) 
VALUES('LEVEL1CCU','CRSG');
INSERT INTO mycurric (CURRIC_CD_CRS,CHILD_CD_CRS) 
VALUES('LEVEL2ACU','CRSA');
INSERT INTO mycurric (CURRIC_CD_CRS,CHILD_CD_CRS) 
VALUES('LEVEL2ACU','CRSF');
INSERT INTO mycurric (CURRIC_CD_CRS,CHILD_CD_CRS) 
VALUES('LEVEL2BCU','CRSG');
INSERT INTO mycurric (CURRIC_CD_CRS,CHILD_CD_CRS) 
VALUES('LEVEL2CCU','LEVEL3ACU');
INSERT INTO mycurric (CURRIC_CD_CRS,CHILD_CD_CRS) 
VALUES('LEVEL3ACU','CRSD');

My attempt which didn't yield what I expected

<html>
<title> my curric TreeExample</Title>

<body>
    <cfform name="myform">
	
	<cfquery name="GetList" datasource="myConn" username="myuser" password="mypad">
            SELECT parent_cd_crs, child_cd_crs from mycurric</cfquery> 
	
	
        <cftree name="treeTest" height="400" width="200" format="html">
        <cftreeitem 
            query="GetList" 
            value="parent_cd_crs,child_cd_crs" 
			parent="parent_cd_crs"
            display="parent_cd_crs, child_cd_crs" 
			queryasroot="NO" expand="no">
        </cftree>
    <hr>

My output looks like this as it doesn't walk up tree

Thank you.
I've been beating myself up trying to noodle out how this tag worked and not getting anything good out of it.
Appreciate your timely response.
I was wondering if I should stay away from the cftree tag and devote my efforts toward a javascript/css solution instead? I could not find a lot of info when I google'd CFTREE.
Which way would you lean?
Thanks again.

yes, certainly a CSS?javascript/Jquery Solution would be much better, if you still wanna use cftree, i suggest you to look into the custom tag cfx_tree which is free and quite advantageous ranther than cftree.

or you can create a custom tag to make recursive calls. but that may slow down the things

Thanks.
I could not find cfx_tree in my searches ... do you have a url?
I found a cf_dbtree ($)

i checked this too

a customtag but worth its usage
