Livewire Select

Livewire component for dependant and/or searchable select inputs

Preview

Installation

You can install the package via composer:

Requirements

This package uses livewire/livewire (https://laravel-livewire.com/) under the hood.

It also uses TailwindCSS (https://tailwindcss.com/) for base styling.

Please make sure you include both of these dependencies before using this component.

Usage

In order to use this component, you must create a new Livewire component that extends from LivewireSelect

You can use make:livewire to create a new component. For example.

In the CarModelSelect class, instead of extending from the base Livewire Component class, extend from LivewireSelect class. Also, remove the render method. You'll have a class similar to this snippet.

In this class, you must override the following methods to provide options for your select input

options() must return a collection of keyed values array items that must have at least the following keys: value and description. For example:

To render the component in a view, just use the Livewire tag or include syntax

You'll see on screen a select input with some custom styles with your defined values

Nothing fancy there. Now, let's make another select input depend on its value.

Create another component following the same process above. In this case, we will create a CarModelSelect with the following options() method.

and define it in the view like this

With these two snippets we have defined a select input that depends-on another select input with name car_brand_id. With this definition, we tell our component to listen to any updates on our car_brand_id input and be notified on changes.

Notice in the options() method the use of two other helper methods: getDependingValue and hasDependency.

getDependingValue('token') will return the value of another field, in this case car_brand_id. If car_brand_id has no value, then it will return null.

hasDependency('token') allows us to check if our component has been specified to depend on other component values. This allows us to reuse the component by checking if a dependency has been specified in our layouts.

For example if we define the same component without the :depends-on attribute, we can use the component and return all car models.

It should look something like this

Searchable inputs

You can define the searchable attribute on the component to change the behavior of your inputs. With :searchable="true" your component will change its behavior to allow searching the options returned in the options() method.

Your input will look something like this

To filter the options in the dropdown, you can use the $searchTerm parameter in the options() method.
