Drupal Field Hierarchy or Fields By Selection

Question

Is there any modules that support a hierarchy for fields? Nodes and fieldable entities in drupal seem so monolithic. For example customers could be categorized into three categories:

Customer A Customer B Customer C

When customer A is selected then I only want specific fields shown according to that selection, and would be different for B and C.

I know I can do this via a hook_form_alter using the ajax callback attribute but wasn't sure if there was something already created for this. I seen the hierarchy module but seems to be specific towards taxonomy.

I think the Conditional Fields module could provide a solution for you.

Define dependencies between fields based on their states and values.

Conditional Fields for Drupal 7 is an user interface to the new States API, plus the ability to modify fields appearance and behavior on certain conditions when viewing content.
