How to Create a Dynamic Link in Vue JS for Dropdown Selections

The Problem

You might find yourself in a situation where you want to use dropdown selections to control the dynamic generation of links. For instance, consider the dropdown for selecting factories and toys. You want to create a link that updates based on the user's choice of factory and toy. The initial code provided illustrates how you might set this up, but requires adjustment to create links that behave dynamically.

Here’s a brief overview of the code structure you have:

This selection allows users to choose their preferences. However, to make the functionality complete, you need a way to turn those selections into a dynamic link. Let’s explore how to achieve this.

The Solution
