Collapsed comments by default

Is there any way to configure the comments (attachments field) to be collapsed by default and when you click the comment link (with count) it expands?

I didn't wanted to reopen an old thread that was talking about something similar: #1057470: Display a comment link instead of all the textareas.

Hint: Maybe using this code
javascript:Drupal.heartbeat.comments.toggleComments(this, COMMENT_NUMBER); return false;
