Multiple lists

HarishBabu

Scenario: I created a module with 2 lists. 
List 1 as Pages

List 2 as Rows

Line items as Column

I want to show only few items in List 2 if specific item is selected in List 1.
Ex: List 1: 1,2,3, -

List 2, 1a,1b,2a,2b,3a,3b
if List 1 selected as 2 
List 2 only shows 2a and 2b

Tried making List 1 as the parent of List 2, There is not possible to split hierarchy in Module

Create a filter module dimensioned by both lists.

Add a boolean line item and select at the intersection of the two list what items should appear for each item of list 1. 

Apply this to the grid as a filter.
