The Problem

You already have a DraggableDiv component that’s visible when the app is launched, but you want to implement a feature that enables users to add more instances of this draggable component by clicking a button. This capability not only improves the user experience but also adds flexibility to the application.

The Solution

Step 1: Setting Up the Template

First, we need to set up the template to include a button and the draggable components. You will use a v-for directive to create multiple instances of the DraggableDiv based on a count maintained in the component's data.

Step 2: Define the Script

Next, you will need to define the script that maintains the state of the component instances. This includes creating a data property for the count of components and a method to increment that count when the button is clicked.

Step 3: Adding Basic Styles (Optional)

Optionally, you might want to add some styling to enhance the visual aspect of your draggable components. However, for this specific feature, the existing styles in DraggableDiv should suffice.

Final Result

With these steps complete, you now have a simple mechanism that allows users to add new instances of your DraggableDiv component dynamically upon clicking the button. The use of the v-for directive streamlines the process and makes it easy to manage the number of components displayed in the interface.
