I prefer in this case use a single line of jQuery.
$("select option:first-child").attr("disabled", "true");
It adds the disabled attribute :
<option value="disabled_options" disabled="disabled">-- choice : --</option>
I would have preferred to do it with formApi but I think this is too much code ...

function helper_form_views_exposed_form_alter(array &$form, FormStateInterface $form_state, $form_id) {
if($form['#id']== 'views-exposed-form-pozdravleniya-taxonomy-term-page-1') {
$form['sort_by']['#title'] = '';

$store_name = $form_state->getValue('name')[0]['value'];
Some input files are multi-value, so you can just use getValue('field_name').

For this problem I think best solution is use module Webform https://www.drupal.org/project/webform, for me this is one of the best Drupal module. Also for this module you have great documentation and demo examples.

just got this sorted out! Decided to drill down to the array structure of the form, and found out that the #ajax element had to be attached to the widget array of the field, like this...
$form['product_line']['widget']['#ajax'] = [...]
Now it works. Another reason I keep crying "better documentation for Drupal"!!! How in the world was anybody ...

For select list, the ajax should be
$form['field_select_box']['widget']['#ajax'] = [

When you are allowed making a php file inside the template you could create a core contact form in UI and use a theme_form_alter() hook to prefill the form fields and add custom submit handlers:
mytheme.theme
use Drupal\Core\Form\FormStateInterface;
function mytheme_form_alter(&$form, FormStateInterface $form_state, $form_id) {
if ($form_id == '...

Think this is an OOP question... so the correct answer is to switch by the type of the instance. In PHP you do this with "instanceof", like here in MappingTest.php:
protected function filterNumericFields(&$fields) {
foreach ($this->view->field as $id => $field) {
if (!($field instanceof NumericField)) {
unset($fields[$...

Based on your comment, it sounds like you want a list of 9 links, and clicking a link sends the users to the node add form for the relevant content type with the Subcategory field already filled in.
As you noted in your question, you can use a menu for this. The challenge is how to pre-fill the first field.
For that, you can use the Prepopulate module.
As ...

I doubt that the array you've found really assigns 2 callbacks. It's rather an array defining a class and a method for a single callback:
'callback' => ['Drupal\foo\BarClass', 'ajaxCallback']
In fact, you can only set one callback in an #ajax element. If you want to override a callback you have to include the overridden callback in your code:
Drupal\foo\...

FormBase is abstract; it implements FormInterface, but doesn't contain methods for:
getFormId
buildForm
submitForm
You need to provide those in your class or PHP will reject it.
...
class Test extends FormBase {
public function getFormId() {
return 'foo';
}
public function buildForm(array $form, FormStateInterface $form_state) {
// Build ...

It's hard to say what is the "best", but you can write a class, add the variables as constants, and then import the class wherever you need it.
For example, in MYMODULE/src/MyVariables.php:
<?php
namespace Drupal\MYMODULE\SharedStuff;
/**
* Defines variables that need to be shared throughout the site.
*/
class MyVariables {
// Seconds ...

hook_entity_extra_field_info() is invoked when either an entity is rendered, or when an entity form is shown to users. See user_entity_extra_field_info() as example.
function user_entity_extra_field_info() {
$fields['user']['user']['form']['account'] = [
'label' => t('User name and password'),
'description' => t('User module account form ...

Just wanted to add that if you overload POST with too many form fields, exceeding your PHP max_post_size, PHP will purge POST. Since that includes submission information, no submission will occur. I had a custom form running in a loop off a database query. If it returns too many rows, the form is too large and cannot be submitted. Doesn't look like that was ...
