Understanding the Challenge

You might have successfully implemented a dropdown using v-model, but when it comes to checkboxes, the challenge increases because multiple selections need to be handled correctly. Let's break it down:

Dropdowns: You can bind a single value easily to v-model.

Checkboxes: They require an array for v-model to store multiple selected values.

If you're trying to bind multiple checkboxes using v-model, you need to ensure that the v-model is linked to an array that can hold all the selected checkbox values.

The Solution

Step 1: Set Up Your Vue Instance

First, you need to create a Vue instance that holds your categories and the array for selected values. Here’s how you can set it up:

Step 2: Create Your HTML Structure

Next, it’s essential to structure your HTML in a way that leverages v-model correctly. Use a v-for loop to generate the checkbox inputs dynamically:

Key Features of the Code

Checkbox Inputs: Each checkbox is bound to the selected array using v-model. This means when a checkbox is checked or unchecked, its corresponding value is automatically updated in the selected array.

Multiselect Dropdown: The same selected array is also used for the multiselect dropdown, showcasing the consistency across input types.
