WooCommerce Customizations

We need to customize our WooCommerce store. We would like to have a dropdown field on our Single Product page that shows all the other variations of that product's different sizes. So the customer can quickly see the prices of the different sizes of the same product. We used to have the products loaded as variable products, but when we filter by size it would only show the smallest size's price instead of the price of the selected sizes. It needs to work like the example attached.
