Cte that creates html nested lists

I have the following cte:

WITH cte AS
(
        SELECT 
            c.ParentIDNo,  
            c.Category,
            c.ChildCategory,
            c.WSWebProductNameIDNo, 
            c.IDNo, 
            0 AS Level,
            CAST('/' + c.Category AS VARCHAR(1000)) as CteName
        FROM WSWebCategory as c
        WHERE c.ParentIDNo IS NULL

        UNION ALL

        SELECT   
            t.ParentIDNo, 
            t.Category,
            t.ChildCategory, 
            t.WSWebProductNameIDNo,
            t.IDNo, 
            cte.Level + 1 AS Level,
            CAST(cte.CteName + '/' + t.ChildCategory AS VARCHAR(1000)) AS CteName
        FROM WSWebCategory t
        INNER JOIN cte ON t.ParentIDNo = cte.IDNo
    )
    SELECT *, REPLICATE('----', Level) + CteName as CteName FROM cte
    ORDER BY cte.CteName

which gives me a list like:

    ---- / Apparatus / Autoclaves

    -------- / Apparatus / Autoclaves / Autoclave Accessories
