Upgrade - how to update old templates to the newest version?

They have classes attached and I see that the newest version doesn't add classes to the elements anymore.

I'm not sure what you're talking about, classes should be imported as before.

Context: we use bespoke components and some defaults (e.g. draggable, resizable etc., style) have been changed.

If your custom components were relying on some previous default property you would just need to update your components but honestly, I don't even remember such a change on any core component.

Let me see some template code not loading properly, please.

Hey, thanks for the quick response. Here is the template generated by v0.14.5 https://jsonblob.com/535ae06f-d4f6-11eb-8bc1-415e99da64cb

This is how it looks https://ibb.co/Zz8qg2J

We've changed some custom components' default attributes and style and changed the dragMode='absolute'. One of the issues is that the old components can't be moved around.

I can provide code samples if needed.

I've setup old vs new version for an existing template:

Thanks for reporting this, @acip.

Great question about Upgrade - how to update old templates to the newest version?. The recommended approach with StyleManager 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
