I have built a multiple select dropdown using livewire 3 and alpine. Most of the code I found on the web and adjusted it to work for me. However, when I adding the model I am setting it by the property name rather then using wire:model and @entangle(). I'm wondering if there is a better way to sync between the component than what I'm currently doing
@props([
'optionValue' => '',
'optionLabel' => '',
'model',
'optionsList' => [],
'selectedOptions' => [],
'label' => null,
'disabled' => false,
])
<div wire:ignore>
@if($label)
<x-input-label class="mb-1" for="{{ $model }}">{{ $label }}</x-input-label>
@endif
<select style="display: none;" id="select">
@foreach($optionsList as $optionList)
<option
value="{{ $optionList[$optionValue] }}" {{ in_array($optionList[$optionValue], $selectedOptions) ? 'selected=selected' : false }}>
{{ $optionList[$optionLabel] }}
</option>
@endforeach
</select>

<input name="values" type="hidden" x-bind:value="selectedValues()">

loadOptions() {
const options = document.getElementById('select').options;
for (let i = 0; i < options.length; i++) {
this.options.push({
value: options[i].value,
text: options[i].innerText,
selected: options[i].getAttribute('selected') != null ? options[i].getAttribute('selected') : false
});
if (options[i].getAttribute('selected') != null) {
this.selected.push(i);
}
}
},
selectedValues() {
return this.selected.map((option) => {
return this.options[option].value;
})
}
}
}
</script>
</div>
I then add it to my livewire component like so
<x-form.multi-select
model="schoolsListForm.grades"
label="Grades"
:optionsList="\Config::get('applications.grades')"
:selectedOptions="$schoolsListForm->grades"
optionValue="id"
optionLabel="name" />
Thanks
