SQL & PL/SQL :: Multiple Rows On A Table To Multiple Columns On One Row

I am attempting to select back multiple values for a specific key on one row. See the example below. I have been able to use the sys_connect_by_path to combine the fields into one field but I am unable to assign them to fields of their own. See the example below

TABLE DETAILS:
Policy id plan name
111 A Plan
111 B Plan
111 Z Plan
112 A Plan
112 Z Plan

My desired result is to be able to show the output as follows

Policy ID Plan_1 Plan_2 Plan_3
111 A Plan B Plan Z PLan
112 A Plan Z PLan
