SQL & PL/SQL :: Query With Connect Path

I am working on a query as below:

CREATE TABLE FDL_SNOP_SCDHUB.TEST_CONN
(
NAME1 VARCHAR2(100 ),
VALUE1 VARCHAR2(4000 ),
ID1 VARCHAR2(200 ) NOT NULL
);
[code]....

I have tried with sys_connect_by_path and wm_concat

with mst as (
select id1,name1,value1 from test_conn c
where ((c.name1='WORKFLOW_TYPE' and NVL2(:p_workflow_type,decode(:p_workflow_type,' SELECT ALL',' SELECT ALL',c.value1),0)=NVL2(:p_workflow_type,:p_workflow_type,0))
or (c.name1='SOURCE_TYPE' and NVL2(:p_source_type,decode(:p_source_type,' SELECT ALL',' SELECT
[code]....

but unable to group it by Id, all comes under one column
