```

    </div>
</div>
```

{
    hasBadges && (
        <div className="flex items-center gap-2 flex-wrap">
            {/* Code Badge */}
            {item.code && (
                <span className="bg-gray-100 text-gray-700 text-xs font-medium px-2 py-0.5 rounded-md">
                    {item.code}
                </span>
            )}

            {/* Stock Badge */}
            {item.stock !== undefined && (
                <span className="bg-blue-50 text-blue-600 text-xs font-medium px-2 py-0.5 rounded-md">
                    Stock:{item.stock}
                </span>
            )}

            {/* Category Badge */}
            {item.category_name && (
                <span className="bg-purple-50 text-purple-700 text-xs font-medium px-2 py-0.5 rounded-md">
                    {item.category_name}

## 🔍 **Conditional Rendering Logic**

### **Badge Display Logic**

```tsx
// Check if we have any badges to show
const hasBadges = item.code || item.stock !== undefined || item.category_name;

// Only render badge row if badges exist
{
    hasBadges && (
        <div className="flex items-center gap-2 flex-wrap">
            {/* Individual badge conditionals */}
        </div>
    );
}
```

### **Individual Badge Conditions**

-   **Code Badge**: Only renders if `item.code` exists
-   **Stock Badge**: Only renders if `item.stock !== undefined`
-   **Category Badge**: Only renders if `item.category_name` exists
-   **Smart Collapse**: If no badges exist, the middle row is completely hidden
