Style Manager don't update background when component is selected

Hi @ronaldohoch the issue here is with your custom type background and the way you're adding it is not correct (proper usage of the API). The addType is mainly for adding new UI inputs, if you don't need a new type of UI (like in your case) you can rely on addBuiltIn to extend the default background properties (you can refer to grapesjs-style-filter for a more advanced usage of addBuiltIn)

@tuongnguyendev your issue seems unrelated, please create a new issue with a reproducible demo.

Hi @artf , I have a problem quite similar to @ronaldohoch when use the latest version of GrapesJS

Thanks for reporting this, @ronaldohoch.

Great question about Style Manager don't update background when component is selected. 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));

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