name :emp_name
item type: list item
elements in list : list_elements : (null) list_item : (null)     
data type : Char
maximum length : 200
and create PROCEDURE :
PROCEDURE POPULATE_LIST_BY_QUERY(P_LIST_NAME VARCHAR2,P_QUERY VARCHAR2) IS
   RG_NAME  VARCHAR2(30) := 'RG_CODE_DESC' ;
   RG_ID    RecordGroup;
   errcode  NUMBER;
   LIST_ID  ITEM;
BEGIN
     RG_ID := FIND_GROUP(RG_NAME);
     IF NOT ID_NULL (RG_ID)
        THEN DELETE_GROUP (RG_ID) ;
     END IF;
     RG_ID   := Create_Group_From_Query (RG_NAME, P_QUERY) ; 
     errcode := Populate_Group (RG_ID) ;  
     LIST_ID := FIND_ITEM (P_LIST_NAME) ;
     POPULATE_LIST (LIST_ID,RG_ID) ;
END;and wrote in trigger WHEN_NEW_FORM_INSTANCE:
  POPULATE_LIST_BY_QUERY('BLK1.emp_name', 'SELECT emp_name,emp_id FROM employees');
create table employees
(emp_no number(10) primary key,
emp_name varchar2(200))
Insert into EMPLOYEES
   (EMP_NO, EMP_NAME)
Values
   (1, 'hhh uuo');
Insert into EMPLOYEES
   (EMP_NO, EMP_NAME)

Hi,
You can try,
POPULATE_LIST_BY_QUERY('BLK1.EMP_NAME', 'SELECT EMP_NAME, EMP_ID FROM EMPLOYEES WHERE EMP_NAME LIKE ''' || <your_search_variable> || '%''');Hope this helps.
