Enable some new modules installed in D8

Hi
I would like to know how I can enable the following plugins for CKEditor:

  • fakeobjects

  • Anchor Link

  • iframe

When I try to enable it does not work, must I do a extra step?
Thanks

in general CKEditor plugins are made out of two parts:

  • The Drupal module
  • The Ckeditor javascript library (usually expressed as dependency of the module)

The general problem is that most of CKEditor plugin Drupal modules are hardcoding the location of the library to /<DRUPAL_ROOT>/libraries/ or /<DRUPAL_ROOT/sites/all/libraries/ and doesn’t allow easily to specify a folder locally to specific sites on a multisite installation (like ours).

So the general woraround is to install the Drupal module locally, and adapt the part of the code that load the Javascript library and point instead to the site’s local libraries folder.
something like

$base_path = \Drupal::service('site.path');
$ckeditor_plugin_name= "Anchor";
$new_path = "/$base_path/libraries/$ckeditor_plugin_name/"

It’s difficult to provide a solution that fits all the CKEditor plugin modules, since it depends how they load the library.

There is another approach I tested for another use case that also can help: Use vendor JS & CSS libraries on multisite installation

Thanks
I will try and see.
