# Nested Comments Thread (with Like and Reply)
## Overview
This block contains a list of comments created by different users. Each user can create a new comment, reply to, or like a parent comment. This block (and its comments database object) can be connected to any data object in your database (e.g., a topic, a product, or a post). Admins (or users with admin access) can manage the comments section by hovering over a comment and clicking on the ellipsis menu to delete the comment.
## 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.
* **new\_nestedcommentsGroup**\
This reusable element contains all of the logic and UI for the nested comments module. It contains four main groups:
* **Group Parent message input**\
This group contains the multiline input for posting a parent `comment`. Clicking on **Button Parent POST** will most the text in **MultilineInput Parent Comment** as a parent `comment`.
* **RepeatingGroup Parent comment**\
This repeating group displays all parent `comments` posted by users (where the parent comment is empty).
* **RepeatingGroup Child comment** displays all children comments (where the parent comment is parent group's comment).
* Clicking on **Text Parent reply button** will show **Group Child message input\_t-comment** and allow the user to reply to a parent `comment`.
* Clicking on **Button Child REPLY** will post the `comment` underneath the parent `comment`.
* Clicking on **Text Parent like button** and **Text Child like button** will show **Popup likes**.
* Clicking on **Group Parent fav comment\_t-comment** or **Group Child fav comment\_t-comment** will like/unlike the comment.
* Clicking on **Group Parent menu\_t-comment** and **Group Child menu\_t-comment** will show a menu to delete a `comment`.
* You should add another statement to the existing conditional statements on these groups: *...and Current user's Role is App Admin*
* **Group Main no comments**\
This group will be visible when **RepeatingGroup Parent comment's** list of comments count is 0.
* **Popup Likes**\
This popup shows a list of users who have liked a `comment`.
## How to set up
* Add a field to the `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 **new\_nestedcomments** 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 Parent 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 Parent POST** is clicked to also link the`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 **new\_nestedcomments** reusable element as an instance on a page.
