I need the action that changed to the value of the field in the contents of my .

In drupal 7 was vbo . In drupal 8 are actions but can not change the fields in the content.

I would like to put it in view and massively change the value of the fields.

It is a module for that?

Hi! I am prett new to drupal, please help :-)

I need to have a structure of nodes that work like this:

THX for any help!
