Question

When I enter the editor and use setComponents or addComponents to add components in the store, the first class of the first element will be added to the class of a certain element inexplicably. Does anyone know the reason? I need help! ! ! image image

That class is coming from your app so there could be thousands of reasons, we can't help you just by looking at 2 screenshots. If you think there is a bug, open the issue correctly (by following the template) and create a reproducible demo.

Thanks for reporting this, @sizhousama.

Great question about Editor's strange behavior!. The recommended approach with Components 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
