How does the property color changes to blue when value changed?

Hi @luziye9 for sure you're using a block/component with a custom style property on it... Anyway, if you're opening a BUG issue, you have to follow the template (grapesjs version, reproducible demo, etc.). So, for now, I'm closing this as an invalid issue.

Thanks for reporting this, @luziye9.

Great question about How does the property color changes to blue when value changed?. The recommended approach with Canvas 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
