How to implement a nested comments feature in Bubble.io?

 

Step 1: Create the Comment Data Type

 

  • Navigate to the 'Data' tab and select 'Data Types'.
  • Click on 'Create a new type...' and name it "Comment".
  • Add the necessary fields:
  • "Content": type 'text', holds the comment text.
  • "Parent Comment": type 'Comment', makes the comment a reply to another.
  • "Author": type 'User', references the user who made the comment.
  • "Created Date": type 'date', records the time the comment was made.

 

Step 2: Design the Comment Element

 

  • Go to your app's Design tab.
  • Create a group where the comments will be displayed.
  • Inside this group, add a repeating group (RG) to list the comments.
  • Set the RG's type of content to 'Comment' and the data source to search for comments where 'Parent Comment is empty' to only show top-level comments.
  • Add text elements and other necessary controls inside the cells to display each comment's content, author, and creation date.

 

Step 3: Implement the Reply Function

 

  • Inside the RG cell, add a 'Reply' button.
  • Create a workflow triggered by this button that either shows a popup or toggles a group within the cell to collect the reply text.
  • Ensure that the workflow associates the new comment with the original by setting its 'Parent Comment' to the current cell's comment.

 

Step 4: Display Nested Comments

 

  • Within each RG cell, add another RG for replies.
  • Set this RG's type of content to 'Comment' and data source to 'Current cell's Comment's replies' (search for comments where 'Parent Comment is the current comment').
  • Design this RG to list replies in a similar way to the top-level comments.

 

Step 5: Add New Comment Functionality

 

  • Provide users with an input field and submit button to add a new top-level comment.
  • Create a workflow that adds the comment to the database with the 'Parent Comment' field empty.

 

Step 6: Manage Visibility and Replies Display

 

  • You may wish to add features such as the ability to Show/Hide replies, Load more comments, and so forth. Implement these with additional workflows and states for better user experience.

 

Step 7: Set Privacy Rules

 

  • Head over to the 'Privacy' section under the 'Data' tab and set up rules for who can view or modify comments.

 

Step 8: Test the Nesting Functionality

 

  • Once everything is set up, test the system by creating comments and replies to ensure they display correctly and are properly nested.
