Predefined background colors when selecting a element with a certain class or div.

Well, you can use a simple select trait type with the list of colors and update its style once is changed. Here you can find all the examples necessary for your case: https://grapesjs.com/docs/modules/Traits.html

Thanks for reporting this, @ikenderham.

Great question about Question: Predefined background colors when selecting a element with a certain class or div.. 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));

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