I need to use Selectize in wordpress ajax.
I have a selecto tag, I want to search by entering words and display the results in a dropdown. It is also possible to select several items and delete them.
I tried to do this with the code below but only the output in console.log is displayed as an array.

<select id="variations" name="variations[]" class="form-control variation-input" multiple></select>

PHP Code:

add_action('wp_ajax_search_terms', function () {
    $terms = get_terms([
        'taxonomy' => 'pa_colors',
        'hide_empty' => false,
        'search' => $_POST['search']
    ]);
    foreach ($terms as $term) {
        $return[] = array($term->term_id, $term->name);
    }
    echo json_encode($return);
    wp_die();
});

Js Code:

    $('.variation-input').selectize({
        plugins: ["clear_button","remove_button"],
        valueField: 'id',
        labelField: 'name',
        searchField: 'name',
        options: [],
        delimiter: ',',
        preload: true,
        persist: false,
        create: false,
        load: function (query, callback) {
            if (!query.length) return callback();
            $.ajax({
                // type: 'GET',
                type: 'post',
                url: sudJs.ajax_url,
                dataType: 'json',
                data: {
                    action: 'search_terms',
                    name: query,
                },
                error: function () {
                    console.log('error');
                    callback();
                },
                success: function (result) {
                    console.log(result);
                    callback(result);
                }
            });
        },
    });

Console.log Return array of terms, but not showing in selectize.
