Retrieve Parent Child Sub-Child recors in SQL Query

Question

I've a self reference table and it has Parent-Child-Subchild relation. I'm getting an output (from second answer http://stackoverflow.com/questions/16031000/get-records-containing-all-the-child-records-in-sql-server) as expected, but it's
displaying results in below format.
<parent id> - <name> - <code>
<child id> - <name> - <code>
<child id> - <name> - <code>
<child id> - <name> - <code>
<child id> - <name> - <code>
<sub child id> - <name> - <code>
<sub child id> - <name> - <code>
<sub child id> - <name> - <code>
I want to display the results like in below format with applying some indent style to distinguish parent\ child\sub-child relationship.
<parent id> - <name> - <code>
<child id> - <name> - <code>
<child id> - <name> - <code>
<sub child id> - <name> - <code>
<sub child id> - <name> - <code>
<child id> - <name> - <code>
<child id> - <name> - <code>
<sub child id> - <label> - <code>
<child id> - <name> - <code>
<child id> - <name> - <code>
Please assist me on foumulating results as expected.

BOL has a good example of doing this in the CTE topic.  See http://technet.microsoft.com/en-us/library/ms175972%28v=sql.105%29.aspx Here is a slightly modified
version of what is in BOL.
CREATE TABLE #MyEmployees
EmployeeID smallint NOT NULL,
FirstName nvarchar(30) NOT NULL,
LastName nvarchar(40) NOT NULL,
Title nvarchar(50) NOT NULL,
DeptID smallint NOT NULL,
ManagerID int NULL,
CONSTRAINT PK_EmployeeID PRIMARY KEY CLUSTERED (EmployeeID ASC)
-- Populate the table with values.
INSERT INTO #MyEmployees VALUES
(1, N'Ken', N'Sánchez', N'Chief Executive Officer',16,NULL)
,(273, N'Brian', N'Welcker', N'Vice President of Sales',3,1)
,(274, N'Stephen', N'Jiang', N'North American Sales Manager',3,273)
,(275, N'Michael', N'Blythe', N'Sales Representative',3,274)
,(276, N'Linda', N'Mitchell', N'Sales Representative',3,274)
,(285, N'Syed', N'Abbas', N'Pacific Sales Manager',3,273)
,(286, N'Lynn', N'Tsoflias', N'Sales Representative',3,285)
,(16, N'David',N'Bradley', N'Marketing Manager', 4, 273)
,(23, N'Mary', N'Gibson', N'Marketing Specialist', 4, 16);
; WITH DirectReports(Name, Title, EmployeeID, EmployeeLevel, Sort)
AS (SELECT CONVERT(varchar(255), e.FirstName + ' ' + e.LastName),
e.Title,
e.EmployeeID,
1,
CONVERT(varchar(255), e.FirstName + ' ' + e.LastName)
FROM #MyEmployees AS e
WHERE e.ManagerID IS NULL
UNION ALL
SELECT CONVERT(varchar(255), REPLICATE (' ' , EmployeeLevel) +
e.FirstName + ' ' + e.LastName),
e.Title,
e.EmployeeID,
EmployeeLevel + 1,
CONVERT (varchar(255), RTRIM(Sort) + '| ' + FirstName + ' ' +
LastName)
FROM #MyEmployees AS e
JOIN DirectReports AS d ON e.ManagerID = d.EmployeeID
SELECT EmployeeID, Name, Title, EmployeeLevel
FROM DirectReports
ORDER BY Sort;
GO
drop table #MyEmployees;
