Using Multiselect Inputs with Livewire 3

This guide explains how to implement multiselect inputs with Livewire 3.

Blade Template

(resources/views/livewire/your-component.blade.php)

Add the following Blade code to your view. The wire:ignore directive is used to prevent Livewire from interfering with the jQuery plugin.

<div class="form-group" wire:ignore>
        <label for="options">Select Options:</label>
        <select class="form-control mb-3 js-example-basic-multiple" multiple id="options">
                <option value="volvo">Volvo</option>
                <option value="saab">Saab</option>
                <option value="fiat">Fiat</option>
                <option value="audi">Audi</option>
        </select>
</div>

JavaScript

Include the following script in your Blade template to handle the change event of the multiselect input. This script will update the Livewire component's property selectedOptions with the selected values.

@script
  <script>
  
       $(document).ready(function() {
          $('#options').on('change', function(e){
              // let selectedValues =  e.target.value;
              let selectedValues =  $(this).val();
              $wire.$set('selectedOptions', selectedValues);
          });
      });
  
  </script>
@endscript

component

Livewire Component (app/Http/Livewire/YourComponent.php)

In your Livewire component class, declare the selectedOptions property.

namespace App\Http\Livewire;

use Livewire\Component;
use App\Models\Attribute;

class YourComponent extends Component
{
    public $selectedOptions = [];

    public function render()
    {
        return view('livewire.your-component');
    }
}

Note

Make sure you have jQuery and the select2 library included in your project.

<!-- Include select2 CSS -->
<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/select2.min.css" rel="stylesheet" />

<!-- Include jQuery -->
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>

<!-- Include select2 JS -->
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/select2.min.js"></script>

<!-- Initialize select2 -->
<script>
    $(document).ready(function() {
        $('.js-example-basic-multiple').select2();
    });
</script>
