How to disable HTML tag scraping in Wordpress?

Question

WordPress

Good afternoon. Can you please tell me how to disable the function of clearing html tags in Wordpress?
For example, I am pasting the following code into a page:

<div itemscope itemtype="http://schema.org/ImageObject">
<h2 itemprop="name">Текст</h2>
</div>

When I save it, Wordpress cleans up the tag attributes and the following code comes out:

<div>
<h2>Текст</h2>
</div>

Thanks in advance.

Answer 1

remove_filter( 'the_content', 'wpautop' ); // Отключаем автоформатирование в полном посте
remove_filter( 'the_excerpt', 'wpautop' ); // Отключаем автоформатирование в кратком(анонсе) посте

It?
Oh yes, this should be written in functions.php (in the same place where the active theme is)
