Pull Request: Unified Responsive Toolbar with Search & Layout Controls

Kanban Ticket: https://hivemq.kanbanize.com/ctrl_board/57/cards/37943/details/

---

Description

This PR transforms the workspace canvas toolbar experience by unifying the search/filter controls and layout controls into a single, collapsible, responsive toolbar. Previously, users had two separate panels competing for space at the top of the canvas. Now, users have a streamlined toolbar that adapts to any screen size while providing quick access to all essential workspace controls.

The enhancement introduces:

• Unified Toolbar: Combined search/filter and layout controls into one cohesive interface at the top-left corner
• Full Responsiveness: Mobile-first design that adapts from 320px phones to 1920px+ desktops with vertical and horizontal layouts
• Collapsible Interface: Reduces canvas footprint when controls aren't needed, maximizing workspace visibility
• Complete Accessibility: Full ARIA disclosure pattern implementation with screen reader support
• Visual Feedback: Icon rotation and adaptive tooltips provide clear directional cues for expansion/collapse

User Experience Improvements

What users gain:

• More Canvas Space: Toolbar collapses to a minimal 56-80px width when not in use, freeing up valuable canvas real estate
• Better Mobile Experience: Full-width vertical layout on mobile devices (< 768px) with touch-optimized 48px tap targets
• Unified Workflow: All canvas controls in one location - no more hunting between separate panels
• Adaptive Design: Toolbar automatically adjusts layout based on screen size without losing functionality
• Clear Visual Cues: Rotated chevron icons (down/up on mobile, left/right on desktop) show expansion direction
• Keyboard Efficiency: Ctrl/Cmd+L shortcut still applies layout even when toolbar is collapsed

Technical Summary

Implementation highlights:

• Migrated layout controls from standalone LayoutControlsPanel into existing CanvasToolbar component
• Implemented Chakra UI responsive syntax (mobile-first) with breakpoints at 768px (md) and 1280px (xl)
• Added WAI-ARIA Disclosure pattern with aria-expanded, aria-controls, and role="region" attributes
• Used useBreakpointValue for responsive props that don't support object syntax (divider orientation, tooltip placement)
• Updated 27 E2E tests and 10 component tests to work with unified toolbar
• Added test-id to settings button and updated Page Objects for reliable E2E testing

BEFORE

Previous Behavior - Separate Control Panels

The old implementation used two independent panels positioned at different corners of the canvas:

Limitations:

• Layout Controls Panel (top-left) and Search Toolbar (top-right) competed for screen space
• Both panels always visible, reducing available canvas area
• No responsive behavior - same layout on all screen sizes caused cramping on tablets/phones
• Inconsistent positioning made workflow less intuitive
• Layout controls panel lacked collapse functionality

---

AFTER

New Behavior - Unified Responsive Toolbar

The new implementation combines both control sets into a single adaptive toolbar that optimizes for every screen size:

1. Desktop View - Collapsed State (>= 1280px)

The toolbar starts in a minimal collapsed state, showing only an expand button with search icon:

Test: cypress/e2e/workspace/workspace-layout-basic.spec.cy.ts - "should display layout controls in workspace"
Screenshot: 1280x800 viewport showing collapsed toolbar at top-left

Key Visual Elements:

• Expand Button: Right-pointing chevron (→) with search icon indicates horizontal expansion
• Compact Size: Only 80px wide, maximizing canvas space
• Top-Left Position: Prime location for frequent access without blocking content

User Benefits:

Users get maximum canvas space for viewing their workspace topology while still having quick access to controls with a single click.

2. Desktop View - Expanded State (>= 1280px)

Clicking the expand button reveals all controls in a horizontal layout:

Test: cypress/e2e/workspace/workspace-layout-basic.spec.cy.ts - "should display layout controls in workspace"
Screenshot: 1280x800 viewport showing expanded toolbar with all controls

Key Visual Elements:

• Search Section: Search input and filter button on the left
• Vertical Divider: Clear visual separation between search and layout sections
• Layout Section: Algorithm selector, apply button, presets, and settings on the right
• Collapse Button: Left-pointing chevron (←) at the far right
• Horizontal Flow: All controls arranged in a single row, max width 1280px

User Benefits:

All workspace controls accessible in one location with clear organization. The horizontal layout is space-efficient and familiar to desktop users.

3. Mobile View - Collapsed State (< 768px)

On mobile devices, the toolbar adapts to vertical orientation:

Test: cypress/e2e/workspace/workspace-layout-basic.spec.cy.ts - "should display layout controls in workspace"
Screenshot: 375x667 viewport (iPhone SE) showing collapsed mobile toolbar

Key Visual Elements:

• Expand Button: Down-pointing chevron (↓) with search icon indicates vertical expansion
• Touch-Optimized: 48px minimum tap target meets WCAG AAA standards
• Full-Width Ready: Button spans available width for easy tapping

User Benefits:

Mobile users get a touch-friendly button that's easy to tap, with clear visual feedback showing the toolbar will expand downward.

4. Mobile View - Expanded State (< 768px)

When expanded on mobile, the toolbar becomes a full-width vertical panel:

Test: cypress/e2e/workspace/workspace-layout-basic.spec.cy.ts - "should display layout controls in workspace"
Screenshot: 375x667 viewport showing full vertical toolbar layout

Key Visual Elements:

• Search Controls: Full-width search input and filter button stacked vertically
• Horizontal Divider: Separates search and layout sections
• Layout Controls: All layout buttons stacked vertically at full width
• Collapse Button: Up-pointing chevron (↑) centered at bottom
• Touch Spacing: Larger gaps (12px) between elements for fat-finger friendliness

User Benefits:

Mobile users get full-width controls that are easy to tap accurately, with vertical stacking that follows natural scrolling behavior. No horizontal scrolling or tiny buttons.

5. Tablet View - Hybrid Layout (768px - 1279px)

Tablets get a semi-vertical layout with row-based control grouping:

Test: cypress/e2e/workspace/workspace-layout-basic.spec.cy.ts - "should display layout controls in workspace"
Screenshot: 768x1024 viewport (iPad) showing tablet-optimized layout

Key Visual Elements:

• Vertical Sections: Main structure is vertical like mobile
• Row Grouping: Within sections, controls arranged in rows (e.g., [Search] [Filter])
• 90% Width: Leaves margin on sides for better visual hierarchy
• Auto-Width Controls: Buttons take natural size, not forced full-width

User Benefits:

Tablet users get an optimized middle-ground that takes advantage of more screen width while maintaining touch-friendly sizing.

Test Coverage

Comprehensive Testing

• 37 tests total, all passing ✅
  • Component tests: 10 tests for CanvasToolbar component
  • E2E tests: 27 tests across 5 workspace layout test files

---

Performance Impact

Positive improvements:

• ✅ Reduced DOM elements: Single toolbar instead of two separate panels
• ✅ CSS-only responsive: No JavaScript calculations for layout changes, uses Chakra UI's responsive props
• ✅ Hardware-accelerated animations: Icon rotation uses CSS transforms (400ms cubic-bezier)
• ✅ Minimal re-renders: Toolbar state isolated with useState, doesn't affect parent components
• ✅ No new dependencies: Leverages existing Chakra UI components

---

Accessibility

Full WCAG 2.1 Level AA compliance:

• ✅ ARIA Disclosure Pattern: Complete implementation with aria-expanded, aria-controls, role="region"
• ✅ Descriptive Labels: All interactive elements have clear aria-label attributes
• ✅ Keyboard Navigation: Tab order logical, all controls keyboard accessible
• ✅ Focus Management: Visible focus indicators on all interactive elements
• ✅ Touch Targets: 48px minimum on mobile (WCAG AAA), 40px on desktop (WCAG AA)
• ✅ Screen Reader Support: Sections announced as landmarks with descriptive labels
• ✅ No Color Reliance: Icon shapes provide meaning independent of color
• ✅ Axe-core Validated: All component tests include accessibility checks with no violations

Accessibility Testing:

• Component test: should be accessible - validates with axe-core
• E2E test: should have accessible layout controls - validates expanded/collapsed states
• E2E test: should have proper ARIA labels - validates all ARIA attributes present

---

Future Enhancements

Optional improvements that could be done later:

• Auto-collapse on mobile: Automatically collapse toolbar after interaction to save screen space
• Swipe gestures: Add touch swipe gestures for expand/collapse on mobile devices
• Persistent state: Remember user's collapsed/expanded preference in localStorage
• Animation refinements: Direction-aware slide animations matching expansion direction
• Reduced motion support: Respect prefers-reduced-motion media query for accessibility
• Additional breakpoint: Fine-tune tablet experience at 992px (lg) breakpoint
• Keyboard shortcut legend: Display available shortcuts in a help dialog
• Landscape optimization: Different layout for mobile landscape orientation

Reviewer Notes

Focus areas for review:

1. Responsive Behavior: Test toolbar at various screen widths (320px, 768px, 1280px) to verify layout changes
2. Accessibility: Verify screen reader announces states correctly, keyboard navigation works smoothly
3. E2E Test Changes: Review the pattern of adding workspacePage.canvasToolbar.expandButton.click() - it's consistent across all 27 tests
4. Icon Transformations: Verify chevron icons rotate correctly at different breakpoints (down/up on mobile, left/right on desktop)

Manual testing suggestions:

1. Open the workspace in your browser
2. Observe the toolbar at top-left in collapsed state (should show expand button with search icon)
3. Click the expand button
4. Verify all controls appear: search, filter, divider, layout selector, apply, presets, settings
5. Click various layout controls to ensure they work
6. Use Ctrl/Cmd+L keyboard shortcut (should work even when toolbar is collapsed) ✅
7. Click collapse button - toolbar should minimize to save space
8. Resize browser window from 1280px down to 768px and 375px - observe layout changes
9. On narrow widths, verify vertical layout with full-width buttons

Quick test commands:

# Run all component tests
pnpm cypress:run:component --spec "src/modules/Workspace/components/controls/CanvasToolbar.spec.cy.tsx"

# Run all layout E2E tests
pnpm cypress:run:e2e --spec "cypress/e2e/workspace/workspace-layout*.spec.cy.ts"

# Run specific E2E test file
pnpm cypress:run:e2e --spec "cypress/e2e/workspace/workspace-layout-basic.spec.cy.ts"

# Check TypeScript errors
pnpm build:tsc

Expected test results:

• Component tests: 10/10 passing ✅
• E2E tests: 27/27 passing ✅
• No TypeScript errors ✅
• No accessibility violations ✅

Migration Notes

For users:

• No migration needed - toolbar starts collapsed by default, click to expand when needed
• All existing keyboard shortcuts continue to work (Ctrl/Cmd+L)
• Layout controls in new location (top-left instead of separate panel) but same functionality

For developers:

• LayoutControlsPanel component removed - functionality now in CanvasToolbar
• Page Object updated: Use workspacePage.canvasToolbar.expandButton.click() before accessing layout controls in E2E tests
• Settings button now has data-testid="workspace-layout-options" for reliable testing
• Responsive props use Chakra UI object syntax: { base, md, xl } for mobile-first approach
