<txp:peg_comments />

In the comments_display form, replace your <txp:comments /> with <txp:peg_comments />.

Attributes are the same as <txp:comments />.
See here for more informations.

<txp:peg_child_comments />

in your comments form, add <txp:peg_child_comments /> at the end. Duplicate whatever attributes you used for <txp:peg_comments />.

<txp:peg_reply_link />

Also add <txp:peg_reply_link /> wherever you see fit; this generates the link to reply to the comment.

<txp:peg_reply_to />

finally, insert <txp:peg_reply_to /> somewhere in your comment_form form.

• wraptag="span" (default: span)
  • used to wrap the generated label, input and links;
• class=""
  • applied to the wraptag;
• label="Your label" (default: Replying to)
  • used as the value of the <label> HTML tag;
• back="Go the initial comment" (default: #)
  • used as a link to the comment you are replying to;
• close="Unchain" (default: ×)
  • used as for link which allow to break the link to the comment you were replying to;
  • add the .peg_replyto_inactive to #peg_replyto_wrap.

Use .peg_replyto_active and .peg_replyto_inactive classes to to hide or alter the display of this tag content in your comment form. .peg_replyto_active is used on reply, .peg_replyto_inactive on simple comment; the second one should be enough to do the following.

Blur the content on simple comment (not a reply)…

.peg_replyto_inactive { opacity: 0.6; }

…or hide it with…

.peg_replyto_inactive { display: none; }

…or…

.peg_replyto_inactive { visibility: hidden; }
