How to Get Selected Items in a Multiselect in Vue.js Components

Are you struggling to implement a multiselect feature in your Vue.js application? If so, you're not alone. Managing selected options in a multiselect dropdown can be tricky, especially when it comes to binding the selected values to your component's data. In this post, we’ll guide you through the process of efficiently retrieving selected items from a multiselect dropdown in Vue.js.

Understanding the Problem

When working with a multiselect dropdown in components, you may want to display a list of options and allow users to select multiple values simultaneously. However, the challenge often lies in correctly binding the selected items to your component’s data model. The provided code snippet highlights this issue:

In the code above, the v-model directive is used to keep track of selected items, but it seems that the binding isn't working as expected. Let's delve into how to correctly implement this feature.

The Solution

To solve this problem, we'll utilize Vue's created lifecycle hook and a more streamlined approach to set up our multiselect. Below are the steps to effectively retrieve selected options.

Step 1: Structure the Template

We will create a template for our component, where we define the multiselect dropdown using the v-model directive. Here’s how the revised template looks:

Step 3: Using Computed Properties

We can utilize computed properties to filter and display the selected items based on user interaction. Update your computed properties as follows:

This computed property allows us to check the user's selections against the predefined list and output the matching items.

By following the steps outlined above, you'll be well on your way to effectively managing selected items in your multiselect dropdown.
