2) Select Specific Parameters

Parameter	Required	Type	Default	Choices	Description
options	No	string			A fixed list, or a dynamic token resolved from WordPress data. Static format: "Option 1 : option_1, Option 2 : option_2". Dynamic tokens: {{posts}}, {{pages}}, {{users}}, {{categories}}, {{tags}}, {{menus}}, {{taxonomies}}, {{post_types}}, with optional REST API parameters (e.g. {{posts?type=book&per_page=100}}). See Dynamic Options.

prefix	No	string			Renders an element before the input. Accepts text (e.g. "$", "https://") or WordPress icon names (e.g. "search", "external", "lock").
suffix	No	string			Renders an element after the input. Accepts text (e.g. "USD", ".com") or WordPress icon names (e.g. "search", "external", "lock").

Dynamic Options

options also accepts a {{token}} that is resolved from WordPress data, for example {{posts?type=book}} for a custom post type. A select renders a single page of REST results (10 by default, 100 at most), so use it for short lists and prefer combobox when the list is larger than one page. See Dynamic Options.

3) PHP Array Schema

Here is an example of how to use the select control in a post meta configuration:

[
    'fieldType' => 'select',
    'name' => 'post_select',
    'fieldLabel' => 'Post Select',
    'required' => false,
    'disabled' => false,
    'hideLabelFromVision' => false,
    'fieldHelpText' => 'Select an option.',
    'className' => 'custom-class',
    'fieldLabelPosition' => 'top',
    'fieldLabelTextTransform' => 'uppercase',
    'options' => [
        ['label' => 'Option 1', 'value' => 'option_1'],
        ['label' => 'Option 2', 'value' => 'option_2']
    ],
    // Or 'options' => 'Option 1 : option_1, Option 2 : option_2'
    'variant' => 'default',
    'multiple' => false,
]

3) Hook-Based Example (Post Meta Config)

It is available to use this control in post meta fields, term meta fields and user settings page and options page fields.

Available hooks:

• native_custom_fields_post_meta_fields
• native_custom_fields_term_meta_fields
• native_custom_fields_user_meta_fields
• native_custom_fields_options_page_fields

add_filter( 'native_custom_fields_post_meta_fields', function( array $configs ): array {
    $post_type = 'book';

    if ( ! isset( $configs[ $post_type ] ) || ! is_array( $configs[ $post_type ] ) ) {
        $configs[ $post_type ] = [
            'post_type' => $post_type,
            'sections'  => [],
        ];
    }

    $configs[ $post_type ]['sections'][] = [
        'meta_box_id'       => 'post_options',
        'meta_box_title'    => 'Post Options',
        'meta_box_context'  => 'side',
        'meta_box_priority' => 'default',
        'fields'            => [
            [
            'fieldType' => 'select',
            'name' => 'post_select',
            'fieldLabel' => 'Post Select',
            'required' => false,
            'disabled' => false,
            'hideLabelFromVision' => false,
            'fieldHelpText' => 'Select an option.',
            'className' => 'custom-class',
            'fieldLabelPosition' => 'top',
            'fieldLabelTextTransform' => 'uppercase',
            'options' => 'Option 1 : option_1, Option 2 : option_2',
            'variant' => 'default',
            'multiple' => false,
            ],
        ],
    ];

    return $configs;
} );
