Steps use checkbox (`- [ ]`) syntax for tracking. + +**Goal:** Add a GroupWidget container to the dashboard that supports panel, collapsible, and tabbed modes for organizing child widgets. + +**Architecture:** GroupWidget extends DashboardWidget, occupies a grid position like any widget, and creates a child sub-layout inside its panel. Children auto-flow or use explicit positions. Collapsible mode mutates Position(4) and triggers layout reflow. Tabbed mode manages multiple child sets with tab-switching visibility. + +**Tech Stack:** MATLAB/Octave, pure figure-based UI (uipanel, uicontrol, axes), JSON serialization, R2020b compatible. + +**Spec:** `docs/superpowers/specs/2026-03-18-dashboard-grouping-and-widgets-design.md` + +--- + +## File Structure + +| Action | File | Responsibility | +|--------|------|---------------| +| Create | `libs/Dashboard/GroupWidget.m` | GroupWidget class — panel/collapsible/tabbed container | +| Modify | `libs/Dashboard/DashboardEngine.m:66-105` | Add `case 'group'` to `addWidget` switch + update `widgetTypes()` | +| Modify | `libs/Dashboard/DashboardSerializer.m:69-114` | Add `case 'group'` to `configToWidgets` + `exportScript` | +| Modify | `libs/Dashboard/DashboardLayout.m` | Add `reflow()` method and `computeChildPositions()` helper | +| Modify | `libs/Dashboard/DashboardTheme.m:37-103` | Add Group* and Tab* theme fields to all 6 presets | +| Modify | `bridge/web/js/widgets.js` | Add `group` type dispatcher | +| Modify | `bridge/web/js/dashboard.js` | Add CSS grid nesting for group containers | +| Create | `tests/suite/TestGroupWidget.m` | Unit + integration tests for GroupWidget | + +--- + +## Chunk 1: Core GroupWidget — Panel Mode + +### Task 1: Scaffold GroupWidget and write panel-mode construction tests + +**Files:** +- Create: `libs/Dashboard/GroupWidget.m` +- Create: `tests/suite/TestGroupWidget.m` + +- [ ] **Step 1: Write failing tests for GroupWidget construction and panel mode** + +```matlab +classdef TestGroupWidget < matlab.unittest.TestCase + methods (TestClassSetup) + function addPaths(testCase) + addpath(fullfile(fileparts(mfilename('fullpath')), '..', '..'));
