Carl's / Scott's Ajax Tree Example Query

Question

Hi,
Hoping someone can assist, I have utilized Carl's and Scott's Ajax tree example, specifically have used the following example from Carl's app, i.e.:
http://apex.oracle.com/pls/otn/f?p=11933:49:4073287192617448::NO:RP::
All is working great but my query is, with the following query, that I am using, i.e.
SELECT "EMP"."MGR" as "MGR",
        "EMP"."EMPNO" as "EMPNO",
        "EMP"."ENAME" as "ENAME" ,
        (select count(*)  from "EMP" "EMP2" where  "EMP2"."MGR" = "EMP"."EMPNO") BranchCount
from
"EMP" "EMP"
where
"EMP"."MGR"  =  :BRANCH_IDI need to also retrieve the LEVEL pseudo-column as well for each record retrieved as I need the LEVEL info for trying to determine at what level of the tree I am at.
I believe you can only use the LEVEL column with a CONNECT BY PRIOR clause.
I would actually like to incorporate the LEVEL column into the above query - is this possible?
If not, can someone pls assist with re-writing the above query using a connect by clause which will still retrieve the same info as Carl's original query.
Thanks.
Tony.

Hello,
Sure just replace the body section of the procedure with something like this.
for c1 in (
select emp_no,emp_name,emp_manager
from emps
order by 2 asc;
     )loop
htp.prn ('<div>' || c1.emp_no || '-' || c1.emp_name || '-' || c1.emp_manager||'</div>');
end loop;
