Question

GrapesJS version

  • I confirm to use the latest version of GrapesJS

What browser are you using?

Chrome 136.0.7103.93

Reproducible demo link

Describe the bug

How to reproduce the bug?

  1. Add multiple image elements to the editor.
  2. Assign the same class name (e.g., class="shared-class") to each image.
  3. Select and resize one of the images.

What is the expected behavior? Only the selected image should be resized, regardless of shared class names or other attributes.

What is the current behavior? All elements sharing the same class name get resized at once, even if only one was selected. It seems the system prioritizes the class name over the ID when setting the style, which leads to unintentional global style changes.

Thanks for reporting this, @jsxOverdose.

Great question about Resizing an element affects all elements with the same class. 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
