Major Feature: Nested Kanban Board
- Parent tasks now appear in each column where they have subtasks
- Provides hierarchical context while maintaining status-based organization
- Eliminates need to choose between hierarchy and status views
Parent Card Features:
1. Multi-Column Presence
- Parent card appears in every column containing its descendants
- Shows "X of Y subtasks in this column" counter
- Automatically updates as children move between columns
2. Expandable/Collapsible
- Click chevron to show/hide children in that specific column
- Each parent instance independently expandable
- Children displayed nested with indentation
3. Visual Distinction
- Thicker orange border (border-2 vs border)
- Bold text styling
- "bg-cyber-darker" background instead of "bg-cyber-darkest"
- Non-draggable (only leaf tasks can be moved)
4. Recursive Display
- getDescendantsInStatus() finds all descendants (not just direct children)
- Handles arbitrary nesting depth
- Works with sub-subtasks and beyond
Technical Implementation:
- Added helper functions:
- getDescendantsInStatus(taskId, allTasks, status)
- hasDescendantsInStatus(taskId, allTasks, status)
- Modified TaskCard component with isParent and columnStatus props
- Updated KanbanColumn to show both parent and leaf tasks
- Only root-level tasks shown (nested children appear when parent expanded)
Display Logic:
- Each column shows:
1. Root parent tasks with descendants in that status
2. Root leaf tasks with that status
- Leaf tasks: tasks with no children
- Parent tasks: tasks with at least one child
Example Usage:
Project "Build Feature"
├─ Backend (2 subtasks in backlog, 1 in progress)
└─ Frontend (1 subtask in done)
Result: Project card appears in 3 columns:
- Backlog: "2 of 3 subtasks in this column"
- In Progress: "1 of 3 subtasks in this column"
- Done: "1 of 3 subtasks in this column"
Documentation:
- Updated README with nested Kanban explanation
- Added v0.1.5 section to CHANGELOG
- Updated version to v0.1.5 in App.jsx
- Moved "Nested Kanban" from roadmap to completed features
This completes the hierarchical task management vision for TESSERACT,
allowing users to see both project structure and status distribution
simultaneously without switching views.
