I'll add search and sorting functionality to make it easier for buyers to find items and for sellers to manage their inventory.

Perfect! I've added comprehensive search and sorting functionality to your sales interface. Here's what's new:

New Search & Filter Features:

For Buyers:

• Search Bar: Search items by name, description, or category with real-time filtering
• Category Filter: Filter items by specific categories or view all
• Sort Options: Sort by name, price, category, or stock level
• Sort Direction: Toggle between ascending and descending order
• Results Counter: Shows how many items match your current filters
• Empty State: Displays a helpful message when no items match the search criteria

For Sellers:

• Inventory Sorting: The seller's inventory list now also respects the sorting preferences
• Item Counter: Shows total number of items in inventory

How It Works:

1. Search: Type in the search box to filter items by name, description, or category
2. Filter by Category: Use the dropdown to show only items from specific categories
3. Sort: Choose to sort by name, price, category, or stock level
4. Sort Direction: Click the arrow button to switch between ascending/descending order
5. Real-time Updates: All filters and sorting happen instantly as you type or change selections

The search is case-insensitive and searches across multiple fields, making it easy for buyers to find exactly what they're looking for. The sorting helps organize items by price (cheapest/most expensive), availability (most/least stock), or alphabetically.
