Drupal 8.x

in entity query,How to use another field as the conditional value?
like this:

        $entity_query=\Drupal::entityQuery("node", 'AND');
        $entity_query->condition("field_A", "field_B", '>');

But this doesn't work

because  in "condition($field, $value = NULL, $operator = NULL, $langcode = NULL)"

$value just is a scalar or array

I can think of solutions: :

   first step ：add query tag

   second step ： Implement query hooks

I have created a rest export for a view. This view is for a specific content type lets say ContentA. The nodes of this content type, are in different languages, some in english and some in a regional language. 

I have added some fields in the rest export for this view and the GET requests shows them. But I want to display the language of the nodes as well. As I said that some nodes are in english and some are in another language. So how can I display the language of a node in the GET requests.

Thanks,

With Panels and Page Manager module it is quite easy get the result however I only can configure specified pages with those modules.

Is it possible to change display of a blocks in a region from row to columns, so from one above another to one next to each other. Or do I need to modify template or maybe there is a module for that?

Seems like I am missing some basics.

I am trying to update to Commerce v2.14 using composer but I am not having any luck. I am currently on v2.13 and Drupal v8.7.7.

When I run the recommended update command I get a message that there is Nothing to Install or Update (since I am already on v2.13):

Hi, please help me solve a problem. I need to display all options from list in content, from checkbos/radiobutton field after I submit it. Sorry for bad English.
