• Improved error handling and graceful fallbacks for missing or invalid data.
• Ensured proper text wrapping and layout styling for long descriptions.

Details of Implementation

1. Dynamic Data Fetching:

   • Subforums are fetched from the endpoint:

     http://35.246.188.121:8080/api/post/get-subforums/non-recursive
     

   • Posts associated with subforums are fetched dynamically using their postId from:

     http://35.246.188.121:8080/api/post/get-post?postId={postId}
     

2. Content Filtering:

   • Post content is filtered to include only items with type: 'text' or type: 'tag'.
   • image and chart types are excluded to focus on relevant textual and tag information.

3. Search and Rendering:

   • Subforums and posts are searchable by their name, title, or description.
   • Posts display:
     • Title: Derived from the post.title or defaults to "Untitled Post."
     • Description: Constructed by concatenating filtered content values.
     • Author: Displayed as post.author.username or defaults to "Unknown."

4. Styling Enhancements:

   • Ensured that long text wraps correctly within containers using:

     overflow-wrap: break-word;
     word-wrap: break-word;
     word-break: break-word;

   • Added padding, margin, and shadows for a visually appealing layout.

5. Error Handling:

   • Skipped invalid or incomplete posts during the fetch process.
   • Default fallback values are applied for missing fields to avoid crashes.
