Dynamically indented text display
depending on you exact set up (which you may be able to modify to suit), you could look into Views Tree module:


  This module provides a tree-based style plugin for Views. It is
  equivalent to the tree-based style template from Views 1.
  
  It is based off of the list style. Although it generates a nested
  view, there is still only a single query run for the view making it
  quite performant.
