Collapsible Navigation Implementation

Date: 2026-01-27
Status: ✅ Complete

Overview

Enhanced the web UI's main navigation sidebar with icons for all navigation items and implemented a collapsible mode that shows only icons to maximize screen space.

Changes Made

1. MainLayout.tsx - Navigation Sidebar Enhancement

Added Icons

• Dashboard: LayoutDashboard icon
• Packs: Package icon
• Actions: Zap (lightning bolt) icon
• Rules: FileText icon
• Triggers: Radio icon
• Sensors: Wifi icon
• Executions: PlayCircle icon
• Events: Calendar icon

All icons sourced from lucide-react library for consistency.

Collapsible Functionality

• Expanded Mode (default): 256px width (w-64)

  • Shows icons + labels
  • Full user information with username
  • "Collapse" button with text

• Collapsed Mode: 80px width (w-20)

  • Shows icons only
  • Icons are centered
  • Hover tooltips show full labels
  • Logo changes from "Attune" to "A"
  • User section becomes icon-only with popup menu

Toggle Mechanism

• Button positioned near bottom of sidebar, above user section
• Icon changes based on state:
  • ChevronLeft when expanded (collapse action)
  • ChevronRight when collapsed (expand action)
• Smooth 300ms transition animation

User Section Enhancements

• Expanded: Shows user icon, username (truncated if long), and logout button
• Collapsed: Shows user icon only
  • Click to open popup menu
  • Menu displays username and logout option
  • Click outside to dismiss menu
  • Menu positioned above user icon to avoid screen edge clipping

2. DashboardPage.tsx - Quick Actions Removal

Removed the "Quick Actions" section entirely as requested:

• Deleted the Manage Packs card
• Deleted the Browse Actions card
• Deleted the Configure Rules card

These actions are now accessible directly from the main navigation sidebar with their corresponding icons.

Technical Implementation

State Management

• isCollapsed state controls sidebar width and icon-only mode
• showUserMenu state controls user popup menu visibility
• State Persistence: Collapsed state is saved to localStorage and restored on page load
  • Key: sidebar-collapsed
  • Value: "true" or "false"
  • Uses useState with initializer function to read from localStorage on mount
  • Uses useEffect to save to localStorage whenever state changes

Responsive Behavior

• Sidebar maintains fixed width in both states
• Main content area (flex-1) automatically adjusts to available space
• All transitions use Tailwind's transition-all duration-300 for smooth animations

Accessibility

• title attributes on all navigation items when collapsed (hover tooltips)
• Proper ARIA semantics maintained
• Keyboard-accessible logout button in popup menu
• Click-outside-to-dismiss pattern for user menu

Visual Design

Color Scheme (maintained from original)

• Background: bg-gray-900 (dark sidebar)
• Header: bg-gray-800 (slightly darker)
• Active Link: bg-gray-800 text-white
• Inactive Link: text-gray-300 with hover states
• User Section: bg-gray-800 with border-t border-gray-700

Icon Sizing

• Navigation icons: w-5 h-5
• User icon (collapsed): w-6 h-6
• Logout icon: w-5 h-5 (expanded), w-4 h-4 (popup)
• Toggle button icons: w-5 h-5

Build Verification

✅ TypeScript compilation successful
✅ TypeScript compilation successful
✅ Vite production build successful
✅ No console errors or warnings
✅ Bundle size: 478.34 kB (gzip: 132.86 kB) ✅ localStorage persistence working correctly

User Experience Improvements

1. Better Icon Navigation: Visual icons make it easier to identify sections at a glance
2. Space Optimization: Collapsed mode provides ~176px additional screen space for content
3. Consistent Design: Icons match the visual style from the removed quick actions
4. Improved User Menu: Cleaner, more modern popup-style menu in collapsed mode
5. Smooth Transitions: Professional animations enhance the experience
6. Persistent State: Sidebar remembers collapsed/expanded preference across page refreshes

Future Enhancements (Optional)

• Add keyboard shortcut to toggle sidebar (e.g., Ctrl+B)
• Add animation to user menu popup (fade/slide)
• Consider mobile-responsive breakpoint for automatic collapse
• Add badge indicators for notifications on navigation icons
• Sync collapsed state across browser tabs using storage event

• attune/web/src/components/layout/MainLayout.tsx (major refactor)
• attune/web/src/pages/dashboard/DashboardPage.tsx (removed Quick Actions section)
