How to merge same Ids data with mysql?

I have records like this after applying joins

id   name   item
1    bil    Books
2    mike   Table
2    mike   chair
3    josh   pen
3    josh   pencil
4    peter  copy

But, I want them to look like this

id   name   item
1    bil    Books
2    mike   Table,chair
3    josh   pen, pencil
4    peter  copy 

How to achieve this?

select id, name, group_concat(item) items
from mytable
group by id, name
