How to recursively (SQL) output parent and child?

There is the following SQL command:

        WITH RECURSIVE menu AS (
            SELECT id, parent_id, name, CAST(name AS CHAR(500)) AS path
            FROM app_menu 
            WHERE name = %s


        SELECT, app_menu.parent_id,, menu.path ||
        FROM app_menu
            JOIN menu 
                ON app_menu.parent_id =   

        SELECT * FROM menu ORDER BY path;'''

Here I display in hierarchical order only the children of the object. How do I get my parents out too. I get an infinite loop if I write:

ON app_menu.parent_id = OR menu.parent_id 

I need to meet one query in SQL
