Role Permission Visual

Role Hierarchy & Permission Visualizer provides a clear, interactive visual breakdown of your Drupal site's access control architecture. Built for Drupal 10 and 11, this module replaces standard permission grids with two comprehensive visualization interfaces: an interactive Organizational Hierarchy Tree and a streamlined Permission Matrix Grid.

Whether managing complex multi-tenant environments or auditing security configurations, this module gives site administrators immediate visual clarity on how permissions cascade across roles.

Features

  • Maps site roles visually based on administrative weight and organizational tiering.
  • Displays real-time active user counts (X Users) assigned to every role.
  • Features smooth, collapsible nodes to expand and audit permission sets without clutter.
  • Automatically recalculates layout dimensions to prevent overlapping text in large sites.
• Comprehensive Permission Matrix Grid:
  • Generates a full cross-reference table mapping roles against site permissions.
  • Features fixed sticky headers for effortless scrolling through long permission sets.
  • Clear visual indicators highlighting active permissions vs. admin bypasses.
• Developer & Security Friendly:
  • Lightweight architecture using Drupal core's PermissionHandler and Role entities.
  • Restricted via standard administer permissions access control.
