What I have tried:

i have used this javascript function but it is only adding products number 1-7:

JavaScript

function addToCart(key) {
    console.log('Key value:', key);

    let item = list.querySelectorAll('.item')[key - 1];
    let name = item.querySelector('.title').textContent;
    let priceText = item.querySelector('.price').textContent;
    let price = parseFloat(priceText.replace(/[^0-9.]/g, ''));
    let image = item.querySelector('img').src; // Get the product image URL
    
    console.log(image);
    
    let container;
    if (key < 13) {
        container = listCarts; // Snacks container
    }

    console.log('Before addToCart:', listCarts);
    
    if (container[key - 1] == null) {
        // Copy product info to list card
        container[key - 1] = {
            name: name,
            basePrice: price,
            price: price,
            quantity: 1,
            image: image, // Store the product image URL
        };
    } else {
        container[key - 1].quantity++;
        container[key - 1].price = container[key - 1].basePrice * container[key - 1].quantity;
    }

    reloadCart();
}

Your issue is related to the condition if 'key < 13' in your code, which specifies that the container should be 'listCarts' only when key is less than 13. The result is that products with keys greater than 7 won't be added to your cart, I have modified your code a little which returns all 13 products -

JavaScript

function addToCart(key) {
    console.log('Key value:', key);

    let item = list.querySelectorAll('.item')[key - 1];
    let name = item.querySelector('.title').textContent;
    let priceText = item.querySelector('.price').textContent;
    let price = parseFloat(priceText.replace(/[^0-9.]/g, ''));
    let image = item.querySelector('img').src; 

    console.log(image);

    let container = listCarts;
    console.log('Before addToCart:', listCarts);

    if (container[key - 1] == null) {        
        container[key - 1] = {
            name: name,
            basePrice: price,
            price: price,
            quantity: 1,
            image: image, 
        };
    } else {
        container[key - 1].quantity++;
        container[key - 1].price = container[key - 1].basePrice * container[key - 1].quantity;
    }

    reloadCart();
}

You can see it working in this fiddle - Show all 13 products [^]
