Drupal 8.x

Hey all,
Drupal 8.2.4 site after migrating from drupal 6.
Try to add a new vocabulary with term.
Everything looks O.k except that the new term don't show up.
I know that they are inserted to the database but for some reason I don't see the new terms.

This is what i am doing.
(short video of the problem...)

I disabled all contrib modules but nothing changed.
Any suggestion for a solution will be great

I want to display all the vocabulary that i've created in the /fr/admin/structure/taxonomy page and each vocabulary linked to the list of terms it containes.

How can i do that ?

The faction of D8 developers who insist on requiring that their contrib modules (and depend libraries) be installed by command line interface (CLI) utilities such as the composer utility only, may eventually destroy Drupal's future as a whole, by alienating the larger audience of potential Drupal users.

Is there a way in views to export the list of nodes and revisions for the given content type? I tried to create "Content revisions" view but it doesn't allow to specify what exact content type do I need. And in the view I get "column reference 'langcode' is ambiguous" SQL error when I try to setup "Get the actual content from a content revision." relationship.

I'm writing a custom field using the Drupal 8 API. Now I need to have a radio button group with some custom classes to each of the different options label. I have already the render array for rendering the radio buttons but can't add some class to the options label.

How can I do this?

In the code block below, you can find a html example on how to draw the field:

I want to ask whether E journal module can be installed on Drupal 8?
