It has no sens. If you wish to have all taxonomies as one array – you should manually convert received object into array:
let arr = Object.values(res).flat();

Sorry, but I don’t understand what is your trouble.
My plugin has only 1 php file, and code is very simple. Try to play with this sources to configure what you need.

Why do you need such changes?
There will be a lot of changes if you want to place needed properties in the root of the json response.

I already fixed this issue.
Who want – can use my own plugin:

Sounds good! Thank you! ??

From my point of view – add additional margin/padding for the element with CSS much more ease and logic than to remove unneeded space from html via styles. Specially when this plugin is using with custom styled checkboxes.

Thank you. But I think would be nice if in the admin panel we will have some options to configure elements content. Or may be plugin will have some wordpress hooks for this? ??

It is not best idea, because when plugin will be updated – this changes will be lost.

Also would be nice to change:

<select name="woorelated_basedon">
  <option selected="<?php echo esc_attr( get_option('woorelated_basedon') ); ?>"><?php echo esc_attr( get_option('woorelated_basedon') ); ?></option>
  <option value="category">Category</option>
  <option value="tag">Tag</option>
</select>

To something like this:

<select name="woorelated_basedon">
  <?php if ( esc_attr(get_option('woorelated_basedon')) == 'tag' ){?>
    <option value="category">Category</option>
    <option selected value="tag">Tag</option>
  <?php } ?>
  <?php if ( esc_attr(get_option('woorelated_basedon')) == 'category' ){?>
    <option selected value="category">Category</option>
    <option value="tag">Tag</option>
  <?php } ?>
</select>

This will remove 3rd unneeded (duplicated) option from related by select.

No, I tried this code, but there are still no results ??

After update to the latest versions (wordpress and relevanssi), when Relevanssi plugin is active – I have no results when I try to view posts by category or tags. When I disable this plugin – I can see all needed posts. Search results seems work normally.

Вот что я в итоге использовал в рабочем проекте:
if (this.href.indexOf(AAPLhome) >= 0 && AAPL_check_ignore(this.href) == true && 1 != jQuery(this).closest('.language-menu-container').length){
это изменение проверят наличие нужного класса у всех родителей элемента, не только у его непосредственного родителя…

Спасибо за быстрый и изчерпывающий ответ )
Вообщем вот моё решение:

заменяем 43 строчку кода в

if (this.href.indexOf(AAPLhome) >= 0 && AAPL_check_ignore(this.href) == true){

на

if (this.href.indexOf(AAPLhome) >= 0 && AAPL_check_ignore(this.href) == true && (this.href).parent().attr('class')=='language-menu-container'){

где language-menu-container – название класса родителя, ссылки в котором будут полностью перегружать страницу, без использования плагина.
