Installation

You can install the package via composer:

composer require etdte/livewire-multiselect

Usage

1) Add LivewireMultiselect\HasSelect trait to your component

class Index extends Component
{
    use LivewireMultiselect\HasSelect;

2) Add select listener to your component

protected $listeners = ['select'];

3) Add variables for an available options and a selected ones to your component

// for selected options - multiple
public ?array $teamFilter = null;
// for selected option - single
public int|string|null $teamFilter = null;

// available options
public ?Collection $teams = null;

4) Add the select to your page

<livewire:multiselect parentId="{{ $this->id }}"
                      name="teamFilter"
                      label="name"
                      :selected="$teamFilter"
                      title="{{ __('Teams') }}"
                      :options="$teams"
                      :multiselect="true"
                      styles="w-full"></livewire:multiselect>

Events

Multiselect component emits a select event, which is caught by HasSelect trait and sets values to a proper variables in your component.
This trait also calls selected function on your component, if it exists, and passes a select name and selected items. You can define a selected method in your component to react on the changes:
Works only if :simpleForm="false"

multiselect

public function selected(string $name, array $value)
{
    if ($name === 'teamFilter') {
        // do something
    }
}

select

public function selected(string $name, int|string|null $value)

Props

Property	Arguments	Default	Example
trackBy	<String> - Used to compare objects.	id	trackBy="id"
label	<String> - Object property in option, that will be visible in the dropdown.	name	label="name"
name	<String> - Used to name inputs & identify multiple selects on a page. Must be the same as a variable name in your component which accepts selected items	required	name="teamFilter"
options	<Illuminate\Support\Collection> - Available options.	required	:options="$teams"
selected	<Array,Integer,String> - Used to define selected options on a page loading. Variable name should be the same as a name prop value.	null	:selected="$teamFilter"
title	<String> - Label title for the select on a page.	null	title="Teams"
multiselect	<Boolean> - Determines if the select is multiple.	false	:multiselect="true"
showEmptyOption	<Boolean> - Determines if an empty option displays on the select. Works only for single selects (:multiselect="false")	true	:showEmptyOption="false"

parentId	<String> - Determines which component a select belongs to. Highly recommended to define it when you have more then one level component depth, with the same selects name on each level.	null	parentId="{{ $this->id }}"
styles	<String> - Classes of the root select wrapper.	col-span-1	styles="w-full"

Additional functionality

You can refresh selected items by calling in your component

// reset component variables
$this->reset('teamFilter');
$this->anotherFilter = [2,3];
// reset options on all component selects
$this->emitTo('multiselect', 'refresh', $this);

// you can also do something like this,
// BUT ALL NOT PASSED SELECTS, WITHIN THE COMPONENT, WILL BE RESET TO EMPTY.
$this->emitTo('multiselect', 'refresh', ['id' => $this->id, 'teamFilter' => [2]]);

You can also refresh available options

$teams = $this->teams->take(3);
// $teams - available options
// 'teamFilter' - select name
// $this->id - component id(parentId)
$this->emitTo('multiselect', 'refreshOptions', $teams, 'teamFilter', $this->id);

Customizing

You can customize a select look by publishing its view
