Implementation Details

HTML Structure with Classes

<div class="section-items parent">                    <!-- Parent level -->
  <a class="nav-link child-1">Regular Item</a>        <!-- Level 1 items -->
  
  <div class="subsection child-1">                    <!-- Level 1 subsection -->
    <button class="subsection-header child-1-header"> <!-- Level 1 header -->
      Subdirectory Name
    </button>
    
    <div class="subsection-items child-1-items">      <!-- Level 1 container -->
      <a class="nav-link sub-item child-2">           <!-- Level 2 items -->
        Nested File
      </a>
    </div>
  </div>
</div>

CSS Hierarchy Control

.parent {
  > .child-1 {
    &.nav-link {
      padding-left: 24px; // Level 1 - regular items
    }

    &.subsection {
      .child-1-header {
        padding-left: 24px; // Level 1 - subsection headers
      }

      .child-1-items {
        padding-left: 8px;   // Reduced padding for child container
        margin-left: 24px;   // Level 1 - subsection items container
        border-left: 2px solid rgba(59, 130, 246, 0.15);

        .child-2 {
          padding-left: 16px; // Level 2 - nested items (optimized)
          font-size: 13px;
          opacity: 0.9;

          &:hover {
            opacity: 1;
            background: rgba(59, 130, 246, 0.05);
          }
        }
      }
    }
  }
}

🔘 Improvement 2: Toggle All + localStorage Persistence

Problem Solved

Implementation Details

Toggle All Button

<div class="navigation-controls">
  <button
    class="toggle-all-button"
    (click)="navigationService.toggleAllSections()"
    [title]="navigationService.areAllSectionsCollapsed() ? 'Expand All' : 'Collapse All'"
  >
    <svg class="toggle-all-icon">
      <!-- Dynamic icons based on state -->
      @if (areAllSectionsCollapsed()) {
        <!-- Expand All Icon -->
        <polyline points="6 9 12 15 18 9"/>
        <polyline points="6 3 12 9 18 3"/>
      } @else {
        <!-- Collapse All Icon -->
        <polyline points="18 15 12 9 6 15"/>
        <polyline points="18 21 12 15 6 21"/>
      }
    </svg>
    <span class="toggle-all-text">
      {{ areAllSectionsCollapsed() ? 'Expand All' : 'Collapse All' }}
    </span>
  </button>
</div>

NavigationService Enhancements

// 💾 LOCALSTORAGE PERSISTENCE
private readonly STORAGE_KEY = 'docs-navigation-state';

// Load states on startup
private loadPersistedStates(): void {
  const stored = localStorage.getItem(this.STORAGE_KEY);
  if (stored) {
    const parsedState = JSON.parse(stored);
    this.collapsedSections.set(new Set(parsedState.collapsedSections));
  }
}

// Save states on every change
private savePersistedStates(): void {
  const state = {
    collapsedSections: Array.from(this.collapsedSections()),
    timestamp: Date.now()
  };
  localStorage.setItem(this.STORAGE_KEY, JSON.stringify(state));
}

// Toggle all sections at once
toggleAllSections(): void {
  const allSections = this.getAllSectionIds();
  
  if (this.areAllSectionsCollapsed()) {
    this.collapsedSections.set(new Set()); // Expand all
  } else {
    this.collapsedSections.set(new Set(allSections)); // Collapse all
  }
  
  this.savePersistedStates(); // Persist state
}

// Enhanced individual toggle with persistence
toggleSection(sectionText: string): void {
  // ... toggle logic ...
  this.savePersistedStates(); // Save every change
}

Professional Styling

.navigation-controls {
  padding: 16px 20px 8px;
  border-bottom: 1px solid rgba(59, 130, 246, 0.1);
  margin-bottom: 12px;

  .toggle-all-button {
    display: flex;
    align-items: center;
    gap: 8px;
    width: 100%;
    padding: 8px 12px;
    background: rgba(59, 130, 246, 0.05);
    border: 1px solid rgba(59, 130, 246, 0.2);
    border-radius: 6px;
    cursor: pointer;
    transition: all 0.2s ease;

    &:hover {
      background: rgba(59, 130, 246, 0.1);
      border-color: rgba(59, 130, 246, 0.3);
      color: var(--primary, #3b82f6);
    }
  }
}
