Drupal 8.x

I have checked both Group and OG modules. Both grouped content , audience. But group module structure different.

I have a feature in drupal 7 , developed totally based on Organic Group module. When I am going to migrate it , I found there is no stable version of OG module available in Drupal 8. So I am facing problems. 

Can I use Drupal 8 Group module to implement this feature which is based on OG module in Drupal 7. If I can implement this feature using Group module in Drupal 8, then how can  I migrate all data ? Because both structure totally different. 

Solution:

The CKEditor doesn't work when you explicitly set the "id" attribute through #attributes. I removed it, and now it works.

Original question:

Hi all,

I'm creating a custom form, which is displayed in a modal, and I want to render a CKEditor field in it, but so far without luck.

This is the gist of the problematic code:

I have a drupal 8 version site (work on progress) and added a bannerslider in the top-header region.
and nothing in the left and right region in the top.

How can I center the Image above the side (now it is alligned left
Tried several bootstrap tricks but with no succes fo far

I am working towards upgrading from D7 to D8 and am now doing practice runs.

I found some weirdly named empty files in sites/default/files named like ewrecrupodupustaprurichilichopharalusachewoclobo , without an extention and with different number of characters for each file.

Any idea of what is going on?

I install manually, without composer and without drush.

I have installed commerce and the plugins with ludwig, webform still needs plugins installed.

EDIT:

New ones get created immediately after deleting...

Folks may have seen recent posts from me asking various twig/class questions as I tried to get my desired home page with a main content section showing article teaser in the Bootstrap Card format.  I finally think I settled on an almost completely out of the box solution using minimal hacks.

The first part of my solution was realizing that if I do NOT use layouts for an article view mode then I get the bootstrap card layout formats in the layout drop-down. That got me my first significant progress.

I have a content type - PSD_availability: It has the below fields:

1. Program_ID

2.Entity reference to PSD_type1 paragraph type

PSD_type1 paragraph type has the below fields:

1. Program_ID

2.Age_group

3. Education level

On th ebackend I have all these data in a table PSD_data. I would like to import all of this table data into PSD_typ1 paragraph and PSD_availability content type. Is there any easy way to do this? I am aware of the feeds  paragraph module but that is not available for D8 yet.
