# No Reply Comments Thread

## Overview

![](/files/-MW1kxbEWGxGkQI_NQJN)

This block is a list of comments or messages by different users, with the ability for a user to create a new comment. It can be added on any object (a topic, a product, etc.).

## Structure

* When this block is added to a page, it is placed within a group called **Blocks container 860 (do not rename)** on the page. This group contains the responsive settings for all blocks.
* The block also comes with a data type called `t-Comments`.  This is the data type that will store all of the comments.
* All of the comments are displayed in **RepeatingGroup t-Comment.**
* **Button POST** creates a new comment.

## How to set up

* Add a field to the `t-Comment` data type that represents the object on which you want users to comment. For example, if you want users to comment on products, you should add a `Product` field.

* Open the **comments\_onelevel** reusable 
* Modify the type of content displayed in the reusable to be whatever object for which you want to show comments. In this case you should make the group type be `Product`.

* Modify the data source for **RepeatingGroup t-Comment** to include whatever filter you need. In this case, you should only include comments that are linked to the Product being displayed.

* Modify the action that runs when the **Button POST** is clicked to also link the `t-Comment` created to the relevant object, in this case the Product that's displayed in the reusable.

* Add a data source whenever you use the **comments\_onelevel** reusable that links to the appropriate object (in this case the `Product` that's displayed on the page).
