How to Use an Object with Vuetify v-select: A Simple Guide

When working with user interfaces in Vue.js, Vuetify provides a powerful component called v-select. This component allows users to select an item from a dropdown list. However, developers sometimes run into a common challenge: how to use an object for the items prop of v-select.

In this post, we'll tackle that question. Specifically, we'll explore whether you can use an object with the items property and, if so, how to set the object key as item-text and the object value as item-value. Let's dive into the solution!

The Challenge: Using an Object with v-select

You might wonder if it’s possible to directly pass an object to the items prop in Vuetify's v-select. The answer is no—at least not in its raw form. However, there is a straightforward method to convert that object into the format that v-select requires for proper functioning.

Why Can't We Use an Object Directly?

The v-select component expects an array of objects, each containing specific properties for text and value (commonly text and value). Directly using an object won't fulfill this requirement, leading to potential issues or the component not rendering as expected.

The Solution: Converting the Object to an Array

Fortunately, it’s easy to convert an object into an array of the required format. You can use JavaScript methods to reshape your data. Here’s how:

Step-by-Step Instructions

Define Your Object: Begin by defining the object you want to use with v-select. It should look something like this:

Use Object.keys(): This JavaScript method retrieves the keys of the object. You'll map over these keys to create an array of objects, where each object has a text (the key) and a value (the corresponding value from the object).

Implement in v-select: Here’s the code that you will use:

What This Code Does

v-model="selected": This binds the selected value to a data property called selected.

:items="...: Instead of passing the object directly, this transforms the object into the necessary array format.

Object.keys(items_obj): Extracts the keys ("Option 1", "Option 2", etc.).

map(...): Constructs a new array where each entry is an object containing a text and value.

Best Practices

While the method above is effective, consider using computed properties or methods for better organization, especially if you'll implement this functionality multiple times. For example:

Then, your v-select would simply become:

Conclusion

Using an object with Vuetify's v-select is not as complicated as it seems! By transforming your object into an array, you can leverage the power of v-select while maintaining clean and effective code.
