I'll improve the MJML generator to better match the structure and styling of your email template. Let's update the code to generate more accurate MJML that properly reflects what you're building in the UI.

Improvements Made

I've significantly improved the MJML generator to better match your email template structure:

1. Enhanced MJML Structure:

   • The generator now properly handles the hierarchy of elements
   • Each element type is correctly translated to its MJML equivalent
   • Attributes are properly mapped from React properties to MJML attributes

2. Better Column Handling:

   • Column layouts now generate proper MJML sections and columns
   • Nested elements within columns are properly rendered

3. Added Preview Functionality:

   • You can now see a preview of how your email might look
   • The preview tab gives you a visual representation alongside the MJML code

4. Improved Error Handling:

   • Better error handling during MJML generation
   • Console logging to help debug any issues

5. Fixed CSS Grid for Columns:

   • Updated the column rendering to use proper grid styling

How to Use

1. Drag elements from the sidebar onto the canvas
2. Select elements to edit their properties in the right panel
3. Arrange and customize your email template
4. Click "Generate MJML" to see the MJML code and preview
5. Copy the MJML code to use with your email service provider

For a complete MJML to HTML conversion in a production environment, you would typically use a server-side MJML renderer or a service like the MJML API.
