I don't know why I added the src attribute to the select-image tag, but it doesn't appear in the 'viewcode' section of GrapesJs

Thanks for reporting this, @Hunganh3012.

Great question about I don't know why I added the src attribute to the select-image tag, but it doesn't appear in the 'viewcode' section of GrapesJs. The recommended approach with GrapesJS is to use the event-driven API.

Start here:

1. Check the GrapesJS documentation for your specific module
2. Look for the on() event listener method
3. Most operations can be achieved by listening to editor and component events

Common patterns:

// Listen for changes
editor.on('change', () => console.log('something changed'));

// Component lifecycle
editor.on('component:mount', (c) => console.log('component ready', c));
editor.on('component:update', (c) => console.log('component updated', c));

If you're still stuck:

• Share a minimal CodeSandbox reproduction
• Include what you've already tried
• Mention your GrapesJS version
