In the Laravel 5.7 application, validate with the tinyMCE editor

Hello,
In my application Laravel 5.7 I use the laravel-jsvalidation plugin (https://github.com/proengsoft/laravel-jsvalidation/wiki/Basic-Usage)
and it worked well,
I needed to include the textarea entry as a tinyMCE editor and use i with validation and implemented it with 2 textarea entries:

{{Form :: textarea (& # 39; description & # 39 ;, isset ($ vote-> description)? $ Vote-> description: & # 39; & # 39 ;, [ "class"=>"form-control editable_field textarea_input ", "rows"=>"0", "cols"=> 120, "id"=>"description", "autocomplete"=>"off", "style"=>"width:0; height:0" ] )}} {{Form :: textarea (& # 39; description_container & # 39 ;, isset ($ vote-> description)? $ Vote-> description: & # 39; & # 39 ;, [ "class"=>"form-control editable_field textarea_input ", "rows"=>"5", "cols"=> 120, "id"=>"description_container", "autocomplete"=>"off" ] )}}

HTML:

where 1st textarea is for sending forms, since the content entered is copied into it from 2nd textarea, which is used as

TinyMCE editor.
In the definition of tinyMCE I added rows:

configuration: function (editor) {
editor.on (& # 39; change & # 39 ;, function () {
var current_context = tinymce.get (by_selector_container) .getContent ()
$ (& # 39; # & # 39; + by_selector) .html (current_context);
});
}

Code (JavaScript):

where by_selector_container and by_selector are the names of these text area entries. It works, but the only problem that on the page I can see the first entry of the text area,
even though I try to hide it by setting wight.width to 0 with the style of my previous code, but anyway
I still see a small text entry, which I want to hide: https://imgur.com/a/43FRFJU

I tried using CSS styles in the declaration of the first text area entry to set

"style" => "display: none"

HTML:

The textarea entry was hidden, but the validation does not work at all.

How to hide it this small text entry with validation work?

Thank you!
