## 💻 **JAVASCRIPT FUNCTIONALITY**
**Need to add to pos.blade.php script section:**

### **✅ 1. Setup Function:**
```javascript
function setupProductSearch() {
    const productSearchInput = document.getElementById('productSearch');
    const displayLimitSelect = document.getElementById('productDisplayLimit');
    
    if (productSearchInput) {
        productSearchInput.addEventListener('input', function() {
            filterProductsDisplay();
        });
    }
    
    if (displayLimitSelect) {
        displayLimitSelect.addEventListener('change', function() {
            filterProductsDisplay();
        });
    }
}
```

### **✅ 2. Filter Function:**
```javascript
function filterProductsDisplay() {
    const productSearchInput = document.getElementById('productSearch');
    const displayLimitSelect = document.getElementById('productDisplayLimit');
    const searchQuery = productSearchInput ? productSearchInput.value.toLowerCase().trim() : '';
    const displayLimit = displayLimitSelect ? displayLimitSelect.value : 'all';
    
    let filteredProducts = productsData;
    
    // Apply search filter
    if (searchQuery) {
        filteredProducts = productsData.filter(product => 
            (product.name && product.name.toLowerCase().includes(searchQuery)) || 
            (product.sku && product.sku.toLowerCase().includes(searchQuery)) ||
            (product.description && product.description.toLowerCase().includes(searchQuery))
        );
    }
    
    // Apply display limit
    if (displayLimit !== 'all') {
        const limit = parseInt(displayLimit);
        filteredProducts = filteredProducts.slice(0, limit);
    }
    
    // Apply current category/brand filter if active
    if (currentFilter !== 'all') {
        if (currentFilter.startsWith('category-')) {
            const categoryId = currentFilter.replace('category-', '');
            filteredProducts = filteredProducts.filter(p => p.category_id == categoryId);
        } else if (currentFilter.startsWith('brand-')) {
            const brandId = currentFilter.replace('brand-', '');
            filteredProducts = filteredProducts.filter(p => p.brand_id == brandId);
        }
    }
    
    renderProductGrid(filteredProducts);
}
```

### **✅ 3. Initialize Function:**
```javascript
// Add to existing DOMContentLoaded event
document.addEventListener('DOMContentLoaded', function() {
    setupProductSearch();
});
```
