Custom Select

Heavily based on Tailwind UI's custom selects, the custom-select component provides a nice alternative to the native select menu. Using this menu will provide your select menus with search functionalities and custom option markup while still providing usability functionalities such as keyboard navigation.

The custom select component requires Alpine.js and Popper.js, as well as some custom JavaScript written into the package to work. Ensure you have the proper directives in your layout file. In production, we recommend you install and compile the JavaScript libraries before you deploy:

{tip} See the JavaScript Dependencies section for more information on installing them.

You can use the select menu by providing some basic options.

<x-custom-select :options="['foo', 'bar']" />

This will output a custom select menu with options for foo and bar. The menu is toggled open and closed by using a <div> element with a role="button" attribute, and renders each option in an <li> tag inside of a <ul>. We have done our best to include all of the necessary aria attributes for accessiblity, but we are by no means accessibility experts. If you notice any accessibility issues, please submit a PR to the github repository to fix them.

The custom select component accepts either an array or collection via the options attribute. You may also render the options yourself via the default slot in the component. If you provide an array of strings, the component will use the strings as both the key and values of the options. For most cases however, you should provide an array of keyed arrays for each option, or you can even pass in an array of Eloquent models as options.

<x-custom-select :options="[
    ['id' => 'foo', 'name' => 'Foo'],
    ['id' => 'bar', 'name' => 'Bar'],
]" />

<!-- using models -->
<x-custom-select :options="\App\Models\User::get(['id', 'name'])" />

By default, the component will look for an id key for the option value, and a name key for the option text. When you are using Eloquent models for options, sometimes this won't work. For this reason, you can specify which keys the option should use for the value and label of the option via value-field and label-field.

If you want more control over the display of an option, you can render your options manually in a @foreach loop and use the <x-custom-select-option> component to render each option.

<x-custom-select name="foo">
    @foreach ($options as $option)
        <x-custom-select-option value="{{ $option->id }}" label="{{ $option->name }}">
            <span class="italic">{{ $option->name }}</span>
        </x-custom-select-option>
    @endforeach
</x-custom-select>

{note} It is important to still pass in the label prop to each option as our JavaScript will use that to determine the text to display for the selected option.

By default, when an option is selected it will display the same text that is provided to it on the label prop on the select's trigger. If you want to display something different for the selected option, you may provide a value to the selected-label prop on the option. This is also possible when not using the options slot on the select by specifying the selected-label-field prop on the custom select.

<x-custom-select 
    name="foo"
    :options="[
        ['id' => 'foo', 'name' => 'Foo', 'short_name' => 'F'],
        ['id' => 'bar', 'name' => 'Bar', 'short_name' => 'B'],
    ]"
    selected-label-field="short_name"
/>

In the example above, when an option is selected, the value for the option's short_name will be displayed on the select's trigger instead of the option's name field.

You may disable specific options by setting disabled to true on the option:

<x-custom-select :options="[['value' => 'foo', 'text' => 'Foo', 'disabled' => true]]" />

You can use a different key for disabled on the option, by specifying it via the disabled-field attribute on the select.

<x-custom-select :options="[['id' => 'foo', 'name' => 'Foo', 'inactive' => true]]" disabled-field="inactive" />

You can specify an option as an "optgroup" header by using a true value on an is_opt_group key on the option:

<x-custom-select :options="[
    ['name' => 'Opt Group', 'is_opt_group' => true],
]"/>

{tip} You can use a different key for the opt group by specifying it for the is-opt-group-field on the select.

{note} As of v7, you should flatten your array of options as the custom select will no longer render an opt group's options automatically.

You may provide search functionality on a custom select by setting searchable on the component to true.

<x-custom-select :options="$options" searchable />

This will provide basic search functionality, which will hide any non-matching options as the user types.

{note} By default searchable is set to true on the select component.

If you use Livewire, you can easily add server-side filtering of options via the livewire-search prop on the component.

<x-custom-select :options="$options" searchable livewire-search="handleSearch" />

In this example, this will require you to have a method called handleSearch on your livewire component. Our JavaScript will call that method via livewire's JavaScript API, passing it the value of the current search term. Your livewire component should filter out the options based on the search. The select component debounces the search input so each keystroke is not triggering another ajax request to your server.

You can easily make a select accept multiple selected options by using the multiple attribute.

<x-custom-select :options="$options" multiple />

With multiple selects, you may limit the number of options a user may select with the max-selected prop.

<x-custom-select :options="$options" multiple :max-selected="3" />

In this example, the user will only be able to select a maximum of 3 options.

{note} The component expects an integer value, so be sure to pass an integer type as the value.

With a multiple select, you may require the user to select a minimum amount of options. You can specify this via the min-selected prop.

For times that you want to allow users to clear the select option(s), you can mark a custom select as optional. This works for both single and multi-select modes, and provides a clear button next to the selected option text.

<x-custom-select :options="$options" optional />

As of v4, the custom-select component makes use of Popper.js for positioning the select menu. This should remove the need for fixed positioning the select menu now. In addition to positioning the menu when opened, Popper.js will also re-position the menu as needed when the page is scrolled.
