<p>This plugin lets you provide the user with search suggestions based on the information entered in the search field.</p>
<p>It adds an AJAX call to the search form, returning matches for the current search query from the database.<br />
There is no change of template files necessary as this plugin hooks in the existing WordPress API to unfold its magic.</p>
<h4>Translations</h4>
<p>I will be more than happy to update the plugin with new locales, as soon as I receive them!<br />
Currently available in:</p>
<ul>
<li>English</li>
<li>Deutsch</li>
<li>Czech</li>
</ul>

WP Search Suggest

С плагином интернет-магазина WP Shop работает отлично.

Чтобы саджест-поиск не искал в ненужных типах записей в файл functions.php достаточно включить функцию-фильтр, в которой настроить WP Search Suggest под себя:


    `/*
    * Customize plugin WP Search Suggest
    */
    function wp_search_suggest_custom($query_args) {

        $query_args += [
            'post_type' => ['post', 'page'],
            'posts_per_page' => 10,
        ];

        return $query_args;
    }
    add_filter( 'wpss_search_query_args', 'wp_search_suggest_custom');`

Отличный плагин для поиска по товарам с подсказками

I like this simple Plugin, I only would wish to have more results or to set an option for this ;)

Simple is the Best!

Great and clean plugin!

Provides title suggestions while typing a search query, using the built-in jQuery suggest script.

JS Categories List Widget

Haven't seen any problems running this with WordPress 4.9.8, even though it's marked as untested for a long time.  It must have been well written.

Works well with 4.9.8

A simple Gutenberg block and JS widget (can be called from posts) for displaying categories in a list with some effects.
