When designing forms for websites, it’s common to want to allow users to select multiple items along with quantities. Imagine a scenario where users can select fruits from a list such as Apple, Banana, and Cherry, and specify how many of each they want to purchase. However, implementing this feature can be tricky. Let’s dive into how to create a multiple select box that's paired with quantity inputs in a streamlined way.
