1. Unified Interface Design**
```html
```
### **โ
2. JavaScript Integration**
```javascript
// Product data from server
const products = @json($products);
document.addEventListener('DOMContentLoaded', function() {
const productSearch = document.getElementById('productSearch');
const productDropdown = document.getElementById('productDropdown');
const selectedProductId = document.getElementById('selectedProductId');
// Populate dropdown with products
function populateDropdown(products) {
productDropdown.innerHTML = '';
products.forEach(product => {
const option = document.createElement('div');
option.className = 'p-2 border-bottom cursor-pointer hover-bg-light';
option.innerHTML = `
${product.name}
SKU: ${product.sku} | Stock: ${product.current_stock} | SP: MWK ${product.selling_price}
`;
option.addEventListener('click', function() {
selectProduct(product);
});
productDropdown.appendChild(option);
});
}
// Filter products based on search
function filterProducts(searchTerm) {
const filtered = products.filter(product => {
const term = searchTerm.toLowerCase();
return product.name.toLowerCase().includes(term) ||
product.sku.toLowerCase().includes(term);
});
populateDropdown(filtered);
if (filtered.length === 0) {
productDropdown.innerHTML = 'No products found
';
}
}
// Search functionality
productSearch.addEventListener('input', function() {
const searchTerm = this.value.trim();
if (searchTerm === '') {
populateDropdown(products);
} else {
filterProducts(searchTerm);
}
productDropdown.style.display = 'block';
selectedProductId.value = ''; // Clear selection when typing
});
// Show dropdown on focus
productSearch.addEventListener('focus', function() {
productDropdown.style.display = 'block';
if (this.value.trim() === '') {
populateDropdown(products);
} else {
filterProducts(this.value);
}
});
// Hide dropdown when clicking outside
document.addEventListener('click', function(event) {
if (!productSearch.contains(event.target) && !productDropdown.contains(event.target)) {
productDropdown.style.display = 'none';
}
});
});
