We are building a new SharePoint 2013 for our company.

In our termstore we have built a tree to show our organization hierarchy.

I have created a list with three columns to pick up the organization. I want to build a solution like this:

If I pick Company 1 in the first column I want to have only Level A and Level B to choose in the second column. And if I pick Level A I just want to see Level AA and AB in the third column.

1. Company 1
   1. Level A
      1. Level AA
      2. Level AB
   2. Level B
      1. Level BA
      2. Level BB
2. Company 2
   1. Level C
      1. Level CA
      2. Level CB
   2. Level D
      1. Level DA
      2. Level DB

Is there anyone that knows if this is possible to create a solution like this with SharePoint? I am just an ordinary administrator I have no programming competence.
