In Drupal 7, there used to be a checkbox: "Allow comment title". Unchecking that, and there was no comment title.

I am unable to locate a similar setting in Drupal 9.

I've found: How to remove or hide the Subject field for comments?

It explains how to auto-generate the subject field for a comment. This is not what I am asking. I don't want to display any subject field when showing a comment. If you're familiar with how comments work in issues posted on Drupal.org, that is the solution I am looking for.

Edit: In comments, it is suggested that you can do this by navigating to the "Manage display" tab for the comment type. However, this is a screen dump (Drupal 9.4.8) of that tab for the default comment type:

Manage display

I see no obvious way to set the title not to be shown.

    Can't you hide the subject field on the Manage Display tab? Nov 9, 2022 at 0:26
  • That's how you do it. Admin -> Structure -> Comment types -> [COMMENT TYPE] -> manage display. Set the title to not be shown.

A solution is to copy core's comment.html.twig and put it in your theme's /templates folder and remove the <h3{{ title_attributes }}>{{ title }}</h3> line.

  • I agree that this will work, but I really do not want to create a subtheme just to be able to hide the Subject. I would prefer to do this from the administrative GUI. The contributed extension named Manage display let me do that, so I've added that as a self-answer. Nov 19, 2022 at 17:24

If one installs the contributed extension named Manage display the "Subject" field becomes exposed under the "Manage display" tab for a comment. You can then move it to the "Disabled" section to hide it.
