🎯 Recommended Additions

Based on the comparison, here are features worth considering:

High Priority

None - Component has feature parity for common use cases

Medium Priority

For better modal/overflow support:

<livewire:async-select
    :append-to-body="true"
    dropdown-class="z-50"
/>

2. Select All/Clear All (Multiple Mode)

For better UX with many selections:

<livewire:async-select
    :multiple="true"
    :show-select-all="true"
/>

Low Priority

3. Custom Match Logic

Client-side matching customization:

<livewire:async-select
    match-mode="starts-with"  {{-- or "exact" or "contains" --}}
/>

4. Drag & Drop Reordering

For advanced multiple selection:

<livewire:async-select
    :multiple="true"
    :sortable="true"
/>

Migration from Select2

Basic Select2

Select2:

    ajax: {
        url: '/api/users',
        dataType: 'json'
    },
    placeholder: 'Select a user'
});

Livewire Async Select:

<livewire:async-select
    endpoint="/api/users"
    wire:model="userId"
    placeholder="Select a user"
/>

With Multiple Selection

Select2:

$('#mySelect').select2({
    multiple: true,
    maximumSelectionLength: 5,
    allowClear: true
});

Livewire Async Select:

<livewire:async-select
    :multiple="true"
    :max-selections="5"
    :clearable="true"

/>

With Custom Templates

Select2:

$('#mySelect').select2({
    templateResult: formatUser,

});

function formatUser(user) {
    if (!user.id) return user.text;
    return $('<span><img src="' + user.avatar + '"/> ' + user.text + '</span>');
}

Livewire Async Select:

<livewire:async-select wire:model="userId">
    <x-slot name="slot" :option="$option">
