# Nested Comments Thread (with Like and Reply)

## Overview

This module is a list of comments or messages by different users, with the ability for a user to create a new comment, reply, or like a comment. It can be added on any object (a topic, a product, etc.). App admins (or users with admin access) will be able to click on the `... icon` to delete any comment in the thread via a menu focus group.

## Structure

* When this module is added to a page, it has a reusable element inside called `nestedcomments`. This reusable element contains all of the logic and UI for the module.
* Within the `nestedcomments` reusable element, there is another reusable element called `commentsmenufocusgroup`. For more information on how to use `menufocusgroups`, please [click here](https://docs.airdev.co/canvas/assets/reuseables/menufocusgroup).
* The module also comes with a data type called `t-Comments`.  This is the data type that will store all of the comments.
* All of the parent comments are displayed in `RepeatingGroup t-Comment parent` and all of the children comments are displayed in `RepeatingGroup t-Comment`.
* `Button POST` creates a new parent comment.
* `Button REPLY` creates a new child comment.
* `Text Like` likes a comment.
* `Group Option 2 (Delete)` deletes a 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 `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 t-Comment parent` 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 `nestedcomments` reusable that links to the appropriate object (in this case the Product that's displayed on the page).
