Manager to employee filtering using slicer

I have table with empid,empname,managerid

So in report I will show 3 columns in a table and a slicer based on empid.

Now when I select one empid, the respective row will be shown in table but when I choose an empid who is also a manager then all employees under him also should be shown in the table.some employees are top-level,they don't have a manager.

 

Please let me know how to implement this. 

 

sample data

Empid  Empname Managerid

100       Abc

101       XYZ              100

102       MMM           100

104       DDD            106

105       EEE              106

106       KKK
