How to Reset v-autocomplete in Vue to Select the Same Option Multiple Times

When developing applications using Vue.js and Vuetify, it’s common to work with components like v-autocomplete. However, a frequent issue arises when users want to select the same option multiple times. By default, these components do not allow that kind of behavior. If you're facing this problem, you’re not alone.

In this guide, we’ll explore how to modify the v-autocomplete component so that users can select the same option repeatedly. Let's dive in!

Understanding the Problem

The v-autocomplete component is designed for selecting items from a dropdown list. While you can select multiple distinct options, it does not permit selecting the same option twice. This limitation can hinder the user experience, especially in applications where repeated selections of the same item are necessary—like triggering multiple informational boxes based on user choices.

Example Scenario

Imagine you are building an application where users choose templates from a selection box. Each time a template is selected, an additional info box appears on the screen. However, because the v-autocomplete component doesn’t allow the same template to be selected multiple times, this leads to a frustrating experience for the user.

The Solution

To resolve this issue, we can implement a workaround. The idea is to maintain an array dedicated to holding the selected items, along with a single variable to represent the current selection for the v-autocomplete. Every time a user selects an option, we will push this value into our array, reset the main selection variable, and thus allow repeated selections of the same option.

Step-by-Step Implementation

Here’s how to set this up:

Vue Component Setup: Use a data structure that holds both the selected item and the array of previously selected items.

Resetting the Selection: After a selection occurs, reset the main selection variable to allow for new selections.

Example Code

Below is the modified code snippet demonstrating how to implement this in your Vue application:

And the corresponding Vue instance:

Key Elements to Note:

v-model: The value characterizes the current selection.

onChange() method: This method pushes the selected value into the values array and resets value to null for allowing repeated selections.

Conclusion

By following the provided steps, you can effectively allow users to select the same item multiple times using the v-autocomplete component in a Vue.js application. This small tweak can significantly improve user experience and is a great example of how understanding and manipulating components can provide tailored functionalities for your applications.
