# HTML Tags Display Fix

## Issue
HTML tags were showing as raw text in the support ticket conversation threads instead of being rendered properly or stripped cleanly.

## Root Cause
The application was using `dangerouslySetInnerHTML` to display ticket descriptions and message content, but when the HTML content contained malformed or unwanted tags, they would display as raw text instead of being rendered.

## Files Fixed

### 1. Support Tickets List (`src/app/(portal)/support/page.js`)
**Problem**: Ticket descriptions showing HTML tags in the preview
**Fix**: 
- Replaced `dangerouslySetInnerHTML` with `stripHtml()` function
- Added `truncateText()` for better preview display
- Added proper imports for HTML utility functions

### 2. Individual Ticket Page (`src/app/(portal)/support/[id]/page.js`)
**Problem**: HTML tags showing in conversation messages and ticket description
**Fix**:
- Replaced `dangerouslySetInnerHTML` with `htmlToText()` function for descriptions
- Used `htmlToText()` for message content to preserve line breaks
- Added `whitespace-pre-wrap` CSS class to maintain formatting
- Added proper imports for HTML utility functions

### 3. New HTML Utilities (`src/utils/html-utils.js`)
**Created utility functions**:
- `stripHtml()` - Removes all HTML tags completely
- `htmlToText()` - Converts HTML to plain text while preserving line breaks
- `sanitizeHtml()` - Allows only safe HTML tags (for future use)
- `truncateText()` - Truncates text with ellipsis

## Changes Made

### Before:
```jsx
// Raw HTML display (problematic)
<div dangerouslySetInnerHTML={{ __html: ticket.description }} />

// Simple regex replacement (loses formatting)
<p>{message.content?.replace(/<[^>]*>/g, '') || 'No content'}</p>
```

### After:
```jsx
// Clean text display with proper formatting
<div className="whitespace-pre-wrap">
  {htmlToText(ticket.description) || 'No description available'}
</div>

// Truncated preview for lists
<div className="line-clamp-2">
  {truncateText(stripHtml(ticket.description), 120)}
</div>
```

## Benefits

1. **Security**: No more `dangerouslySetInnerHTML` usage
2. **Clean Display**: HTML tags no longer show as raw text
3. **Preserved Formatting**: Line breaks and basic formatting maintained
4. **Consistent Truncation**: Proper text truncation in list views
5. **Reusable Utilities**: Functions can be used throughout the app

## Testing

- ✅ Support ticket list shows clean descriptions
- ✅ Individual ticket conversations display properly formatted text
- ✅ Line breaks are preserved in messages
- ✅ No HTML tags visible in the UI
- ✅ Text truncation works correctly in previews

## Future Improvements

If you need to support rich text formatting in the future, consider:
1. Using the `sanitizeHtml()` function to allow safe HTML tags
2. Implementing a proper rich text editor
3. Using markdown for user input instead of HTML
